Answer: x = -11

Explanation:

Expand the expression (distributive property): 3 - 9x = -8x + 14

// subtract 14 from both sides = -11

// add 9x on both sides = x

Simplify: x = -11

Answer:


x=-11

Explanation:

1) Rearrange Terms


3(-3x+1)=2(-4x+7)

2) Distribute


-9x+3=2(-4x+7)

3) Distribute


-9x+3=-8x+14

4) Subtract 3 from both sides of the equation


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

5) Simplify

A. Subtract the numbers


-9x=-8x+14-3

B. Subtract the numbers


-9x=-8x+11

6) Add 8x to both sides of the equation


-9x+8x=-8x+11+8x

7) Simplify

A. Combine like terms


-x=-8x+11+8x

B. Combine like terms


-x=11

8) Divide both sides of the equation by the same term


(-x)/(-1) =(11)/(-1)

9) Simplify

A. Cancel terms that are in both the numerator and denominator


x=(11)/(-1)

B. Divide the numbers


x=-11
