A triangle has one side that measures 9 units, another side that measures x, and a third side that measures 2 units more than x. The perimeter is 29 units.

Which equation would we use to find the value of x?

x + x + x + 2 + 9 = 29
x + x + x + 2 = 29
x + x + 2 + 9 = 29
x + x + 2 = 29

x + x + 2 + 9 = 29

(That simplifies to 2x + 11 = 29, so 2x = 18 and x = 9.)
