simplify
-12x -8 = 18x - 18
add 12x to both sides
-12x +12x -8 = 18x +12x - 18
-8 = 30x -18
now add 18 to both sides
-8 + 18 = 30x - 18 + 18
10 = 30x
divide both sides by 30
x = 1/3

-4(3x + 2) = 3(6x - 6)
Distribute the -4 and the three:
-12x - 8 = 18x -18
Get the x terms on one side:
-30x = -10
Divide by -30:
x = 1/3

DO YOUR OWN ALGEBRA HW
but ill help anway,
-12x-8=18x-18 (distribute)
add 12x
-8=30x-18
add 18
10=30x
divide by 30 to isolate x
10/30=1/3
x=1/3

(-4)*3x + (-4)*2 = (3)*6x - (3)*6
-12x - 8 = 18x - 18
30x = 10
x = 1/3

-4(3x+2)=3(6x-6)....original equation
-12x-8=18x-18.....simple multiplication
18-8=18x+12x....put the numbers with x on right side
10=30x....simple subtraction and addition
x= (1/3).....simple division

1st step: distribute the negative four and the positive 3 into the brackets (so says my 14 year old, I say multiply the brackets by what's infront of them)
2nd step: now, you have -12x - 8 = 18x - 18
3rd step: now, you have -12x -18x = -18 + 8
4th -30x = -10
5th 30x = 10
6th x = 10 divided by 30 , therefore, x = 1/3

distribute: -12x -8 = 18x-18
move all the x's to one side by adding 12x to both sides and the constants to another by adding 18 to both sides:
30x=10
divide by 30 on both sides:
x=1/3
