write and solve an equation for each problem. The perimeter of a rectangle is 30 inches. If its length is three times its width, find the dimensions

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
