-2(x-3)+4=8x-20
lose the parentheses:
-2x+6+4=8x-20
move all the x stuff to the left, and the numbers to the right:
-2x-8x = -20-6-4
simplify each sides:
-10x = -30
divide by -10 to get x alone:
x = 3
check that it fits the original equation:
-2(3-3)+4=8*3-20
0+4 = 24-20
yep
Solve the following equation:
-2(x-3)+4=8x-20

oh okay but hold on when you got rid of the parentheses did you get 6 because 3*2=6? sorry if I'm wrong ^^;
You're right.
