Question

what is the solution to this equation?
5(x - 4) = 3x + 4
a. x = 12
b. x = -2
c. x = -8
d. x = 3

Explanation:

Step1: Expand left side

$5(x-4)=5x-20$

Step2: Rewrite the equation

$5x-20=3x+4$

Step3: Isolate x terms

$5x-3x=4+20$

Step4: Simplify both sides

$2x=24$

Step5: Solve for x

$x=\frac{24}{2}=12$

Answer:

A. $x=12$
