"The length of a rectangle is twice the length of each side of a square"
__ L=2x


"the width of the rectangle is 1 inch less than the length of each side of the square"
__ W=x-1


"The perimeter of the rectangle exceeds the perimeter of the square by three"
__ 2L+2W=4x+3


substituting __ 2(2x)+2(x-1)=4x+3 __ 6x-2=4x+3 __ 2x=5
