A man is 3 times as old as his son. The sum of their ages is 48 years. How old is the son?

Solution:

4x/4=48/4
x=12 years old

The length of a rectangle is 5m more than twice the width. If the perimeter is 88m, what is the dimension of the rectangle?

Solution:
✍️ P=2L+2W
88m=2(2W+5m)+2W
88m=4W+10m+2W
88m=6W+10m
88m-10m=6W
78m/6=6W/6
W=13m

✍️L=2W+5m
L=2(13m)+5m
L=26m+5m
L=31m

✍️Therefore, the dimension of the rectangle is 13m ×31m.
