The perimeter of a rectangle is 28 ft. The length is 10 ft longer than the width. Find the dimensions. Write a system of linear equations and solve the resulting system. Let x be the length and y be the width.
oh drats non-linear is so much more fun!
where x is length and y is width.
2x + 2y = 28
x - 10 = y
solve with substitution
