The length of a rectangle is k less less than the width. Perimeter is p. Find dimensions.

w for width
L for length
p for perimeter
k a number used in the description relating w and L.
Unknown variables are w and L.

system%28L=w-k%2C2w%2B2L=p%29

You can take advantage of the even number value for the perimeter and just use the given values right-away.

system%28w%2BL=49%2CL=w-3%29

w%2Bw-3=49
2w=46
highlight%28w=23%29
