William is 5 times as old as umaima and is also 8 year older hen umaima. how old is william?

Let S represent William, and M represent Umaima.

S = 5M

S = M + 8

Since they are both values of S, they equal each other.

5M = M + 8

Subtract M from each side

4M = 8

Divide each side by 4

M = 4/2

Umaima is 2; therefore William is 10.
