How do you solve 3(1-3x)=2(-4x+7)?

1 Answer

x=-11

Explanation:

First, expand both sides of the equation.

3-9x=-8x+14

Make sure that the variable, x, is only on one side of the equation. Add 9x to each side.

3 -9x +9x = -8x +14 +9x

3 = 14 +x

Subtract 14 from both sides.

3-14=14+x-14
-11=x

Check the solution:
3(1-3[-11])=2(-4[-11]+7)
3(1--33)=2(44+7)
3(1+33)=2(44+7)
3(34)=2(51)
102=102
