Question

Solve for x: 5(x + 3) = 4(x − 3) A. −18 B. −27 C.−3 D. −6

Answer 1

Answer:

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

Answer 2

Answer:

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
