Michael is 17 years older than John. In 4 years, the sum of their ages will be 49. Write an equation that can used to find Michael's present age.

Let Michael's current age, be M
Then John's is: M - 17
Since in 4 years their ages then will sum to 49, then we have:

Continue to solve for M, Michael's current age.
