Solve for x.<br> 5(x - 3) + 4(x + 3) = 3(x - 1)<br> What’s the answer ?

SSSSS [86.1K]

Answer:

x=0

Step-by-step explanation:

Solve for x.

5(x - 3) + 4(x + 3) = 3(x - 1)

Distribute

5x -15 +4x +12 = 3x-3

Combine like terms

9x -3 = 3x-3

Add 3 on each side

9x -3+3 = 3x-3

9x = 3x

Subtract 3x from each side

9x-3x = 3x-3x

6x =0

Divide by 6

6x/6 = 0/6

x=0
