Solve. 6x + 4(3x – 2) = 6x + 2
1) remove all ( )
6x + 12x - 12 = 6x + 2
2) move all x to the left of = all numbers to the right of =
the sign change of the part you move.
6x + 12x -6x = 2 + 12
3) evaluate
12x = 14
4) divide by the number before the x ( if any )
x = 14 / 12
and that is all Angy

1. 6x+4(3x-2)=6x+2
6x+12x-8=6x+2
18x-8=6x+2
12x-8=2
12x=10
x=10/12 or 5/6
2. You draw a dotted line vertically through x and then shade to the right
3. x/2=-1
multiply both sides by 2 and get x=-2
4. 8-(4x-3)=19
8-4x+3 =19
-4x+11=19
-4x = 8
x=-2
5. draw a vertical line through 3
6. Sub in each ordered pair for x and y until you get a true statement. The solution is A

sorry dude, I am not going to do your home work for you. after math class, go up to the teacher, and tell her you are having problems. See if she will help you with it.
