Answer:

x=2

Explanation:

Let's solve your equation step-by-step.

4(x+3)−4=16

Step 1: Simplify both sides of the equation.

4(x+3)−4=16

(4)(x)+(4)(3)+−4=16(Distribute)

4x+12+−4=16

(4x)+(12+−4)=16(Combine Like Terms)

4x+8=16

4x+8=16

Step 2: Subtract 8 from both sides.

4x+8−8=16−8

4x=8

Step 3: Divide both sides by 4.

4x /4 = 8/4

x=2
