distribute the 3 into (2x + 4) and the 2 into (2x - 6).

3*2x + 3*4 = 2*2x - 2*6

6x +12 = 4x - 12

next, separate into like terms; subtract 12 from 6x +12 and 4x - 12, then subtract 4x from 4x - 12 and 6x + 12

6x - 4x = -12 - 12

2x = -24

divide both sides by 2 to get x by itself

2x/2 = -24/2

x is -12

>>

>>610538884

It's a positive 12 you dipshit! You add the negative 12 to both sides, so plus the negative twelve getting you 24. Answer is positive 12, go kill yourself.

>>610538500

Brackets first.

3 ( 2x + 4) = 2 ( 2x - 6)

3 x ( 2x + 4) = 2 x ( 2x - 6)

6x + 12 = 4x - 12

We want x alone so move the 4x from the right to the left. To move over from one side of the equation to another multiply by - 1.

Eg. 6x = 4x

4x * -1 = -4x

So 6x - 4x = 0

Do the same for the numbers.

12 = - 12

12 + 12 = 0

2x = 12 + 12

( 2x ) / 2 = (12 + 12) / 2

x = 11

The easiest way (if you don't feel like doing actual work) is to use a graphing calculator. Split it into two y= equations, and then see where they intersect.

IE:

y=3(2x+4)

y=2(2x-6)

3(2x + 4) = 2(2x - 6) multiply into paranteses

6x + 12 = 4x -12

Have you taken algebra? You subtract 12 from both sides to get

6x = 4x -24

then you subtract 4x from both sides to get

2x = -24

Simplify

x= -12

Who is the retard again?

>>610539331

A number on the left of the brackets means whatever is inside the brackets is multiplied by that number. We want to make the equation simpler, so we times the number on the outside to those within

>3(2x + 4) = 2(2x - 6) = 6x + 12 = 4x - 12

Next, we want to make one side = 0. Whatever you do to one side, you must do to the other. We're going to add 12 cos its the simplest thing atm to make the right side = 0. 4x is considered a separate number, as it is 4 times whatever x represents. Don't worry about adding 12 to that.

>(6x + 12) = (4x - 12)

>(4x - 12) + 12 = (4x)

>(6x + 12) + 12 = (6x + 24)

>(6x+24) = (4x)

We want to get rid of the 4x on the right handside now. Because x is an unknown number, the sum only affects multiples of x.

>(6x+24) = (4x)

>(4x) - 4x = (0)

>(6x + 24) - 4x = (2x + 24)

>(2x + 24) = 0

We now want something to equal something, as this sum doesn't tell us what x is yet. We want x alone on one side, and the integer figure on the other.

>(2x + 24) = (0)

>(2x + 24) - 24 = (2x)

> (0) - 24 = (-24)

>(2x) = (-24)

Then its as easy as dividing both sides by 2 to get x on its own.

>(2x) = (-24)

>(2x) / 2 = (x)

> (-24) / 2 = (-12)

>(x) = (-12)

Remember when balancing equations, whatever you do to one side, you must do to the other. Now good luck in your GCSE's, kids!

he was right though, even though the backlink stuff screws it up

>>

>>610544063

Correct. I think, TL:DR. Answer is right though

>>

>>610543111

Wait I've figured it out.

3(2x + 4) = 2(2x-6)

3/3(2x + 4 ) = 2/3(2x-6)

2x + 4 = 2/3(2x-6)

2x = 14/3(2x-6)

x=14/3(2x-6)

x = 28x/3 - 84/3

-27x/3 = -84/3

-27x = -84

therefore x = 3,111111111

ashlyn rae. you're welcome

Yeah ny too, then sophomore is geometry, junior is trig, senior is math 12 or precalc. If you were put in advanced math then everything moves back one starting with algebra one on eighth grade. When you because a junior in the advanced program you took pre calc then as a senior calc ab or bc, depending on how well you did year before.

Hey op if you want to check their work just plug the -12 back into the original equation

So 3 (2 (-12)+4)=2 (2 (-12)-6)

2*-12=-24 for both sides so

3 (-24+4)=2 (-24-6)

3 (-20)=2 (-30)

-60=-60

So x does infact =-12

Southern cali here public school. They offered Alg 1 in 7th grade, Geo 8th, Alg2 9th, Function/stats/trig 10, Pre-calc/calc/ap calc your choosing 11th and 12th. Most kids stopped with alg 2 as it was only required to graduate whil some kids took AP calc 11th grade to get college credit and just took 1 less class senior year and got out early every day.

But yea how did you take other classes like Chem/physics/Econ without at least algebra in high school.
