L = 2W-7
L * W = 165
Substitute 2W-7 for L in the second equation and solve for W. Insert that value into the first equation to solve for L. Check by putting both values into the second equation.
the length of a triangle is 7 centimeters less than twice the width. if the area of the rectangle is 165 square centimeters, find the length and width.
