Let the width of the garden be x ft

then the length is x+5 ft.

area = x(x+5)

width of garden with sidewalk = x+4

length of garden with sidewalk = x+9

(x+4)(x+9) - x(x+5) = 76

solve, the x^2 will drop out

(X+4)(x+9)-x(x+5)=76

(x^2+9x+4x+36)-x(x+5)=76

x^2+13x+36-x^2-5x=76

X^2 will drop and we will combine the like terms(13x and -5x) and 36 will go to the other side

8x=76-36

8x=40

x=5

W=5ft

L=10ft since L=x+5
