Question 896754: Given the perimeter P, find the missing measurement.
*The picture is showing a triangle*
One side of the triangle has a ? (because it wants you to find it), Another side has 3(x + 2) and the last side has 5x + 3. The perimeter of the triangle is P = 10x + 3.

a +3(x+2) +(5x+3) = 10x +3
a +3x+6 +5x+3 = 10x +3
a +8x +9 = 10x +3
a +6 = 2x
a = 2x -6
