4(x + 1) + 8 = 24 --- distribute through the parenthesis 4x + 4 + 8 = 24 -- simplify 4x + 12 = 24 --- subtract 12 from both sides 4x = 24 - 12 4x = 12 -- divide both sides by 4 x = 3 check.. 4(x + 1) + 8 = 24 4(3 + 1) + 8 = 24 4(4) + 8 = 24 16 + 8 = 24 24 = 24 (correct) so x = 3

Jeez. how do you do that so fast?

Opening the parenthesis is not necessary $4(x+1)+8=24$ Subtract 8 $4(x+1)+8-8=24-8$$4(x+1)=16$ Divide by 4 $\frac{4(x+1)}{4}=\frac{16}{4}$$x+1=4$ Subtract 1 $x+1-1=4-1$$x=3$
