help me please.

the perimeter of a rectangle is 120 inches. The length exceeds the width by 10 inches. Find the length and the width.
Answered by Ms. Sue
P = 2L + 2W
120 = 2(W + 10) + 2W
120 = 4W + 20
100 = 4W
? = W

Hi Mrs. Sue... I'm still confused with the final answer. Can you make it more simple for me to understand. Thanks.
Answered by Ms. Sue
100/4 = 25

The width is 25.

The length is 25 + 10 = 35

120 = (2 * 25) + (2 * 35)
120 = 50 + 70
