How to solve:
Solve for x:     5(x + 3) = 3x + 23.
Simplify by distributing:     5x + 15 = 3x + 23.
Subtract 3x from both sides:     5x + 15 - 3x = 3x + 23 - 3x.
Simplify:     2x + 15 = 23.
Subtract 15 from both sides:     2x + 15 - 15 = 23 - 15.
Simplify:     2x = 8.
Divide both sides by 2:     2x/2 = 8/2.
Simplify:     x = 4.
