simplify 1/5 (20x + 50) to 20x + 50/5

subtract 2 from both sides

factor out the common term 10

simplify 10(2x + 5)/5 to 2(2x + 5)

simplify 68 - 2 to 66

divide both sides by 2

simplify 66/2 to 33

subtract 5 from both sides

simplify 33 - 5 to 28

divide both sides by 2

simplify 28/2 to 14

Answer: x = 14
