In 56 years, kevin will be 9 times as old as he currently is. how old is kevin currently?

Hello from MrBillDoesMath!

Discussion:

Let "x" be Kevin's current age. From the probel statement:

x + 56 = 9x.

Subtract "x" from each side:

(x-x) + 56 = 9x -x  or

0 + 56 = 8x.  Divide each side by 8:

56/8 = x  or

7 = x

Thank you,
