The perimeter is the sum of its sides.
7 + x + (x+2) = 29
[subtract 7 from both sides]
x + x + 2 = 22
[subtract 2 from both sides]
x + x = 20, or 2x = 20
[divide both sides by 2]
x = 10
7 + x + (x+2) = 29
[subtract 7 from both sides]
x + x + 2 = 22
[subtract 2 from both sides]
x + x = 20, or 2x = 20
[divide both sides by 2]
x = 10

The perimeter is the sum of the lengths of the sides.
7 + x + (x+2) = 29
9 + 2x = 29
2x = 20
x = 10
7 + x + (x+2) = 29
9 + 2x = 29
2x = 20
x = 10
