Solve for x.

4(2x + 1) = 3(x + 8)

a. x = 20
b. x = 7
c. x = 5
d. x = 4

In order to solve for x, our long term goal is essentially trying to isolate x, or to have only x on one side.

First of all, let's start by distributing numbers.
4(2x + 1) = 3(x + 8)
8x + 4 = 3x + 24

Subtract both sides by 3x:
5x + 4 = 24

Subtract both sides by 4:
5x = 20

Divide both sides by 5:
x = 4

There we go. That wasn't so bad, was it?
Let me know if you need any further explanation :))
