Question

Solve for X
3(x-1) = 2(x+3)
A. x=15
B. x=8
C. x=12
D. x=9

Answer 1

Answer: x=7

Explanation:

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

3x-3=2x+4 use distributive property

x-3=4 put x values on same side

x=7 put integers on same side

Answer 2

Answer: D. x=9

Explanation:

Distribute the 3 on the left side of the equation

3x-3 = 2(x+3)

Distribute the 2 on the right side of the equation

3x-3 = 2x+6

Subtract 2x on both sides to get the x's on one side of the equation

x-3 = 6

Add +3 on both sides to isolate x

x = 9
