Solve for x: 5 (x + 3) = 4 (x - 3)

A. - 18

B. - 27

C.-3

D. - 6

x=-27

Step-by-step explanation:

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

Step 1: Simplify both sides of the equation.

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

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

5x+15=4x+-12

5x+15=4x-12

Step 2: Subtract 4x from both sides.

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

x+15=-12

Step 3: Subtract 15 from both sides.

x+15-15=-12-15

x=-27

B

Step-by-step explanation:

Given

5 (x + 3) = 4 (x - 3) ← distribute both sides

5x + 15 = 4x - 12 (subtract 4x from both sides)

x + 15 = - 12 (subtract 15 from both sides)

x = - 27 → B
