Solve:

the width of a rectangle is 15 cm less than the length. the perimeter is 98 cm. find the width and length of the rectangle.

X+x+x-15+x-15=98 simplifies to 4x-30=98 move the 30 over 4x=98+30 simplify and you have 4x=128 divide both sides by 4 and you're left with x=32 which is your length, your width is 32-15 which is 17.
