64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44.
Write an equation to determine Sarah's age (a).

Find Sarah's age

Sarah is older than 44.
Her age, a, minus 44 is a positive number.

a - 44 is positive

4 times the difference is 4(a - 44)
That equals 64, so we have

4(a - 44) = 64

Divide both sides by 4

a - 44 = 16

Add 44 to both sides

a = 60

Sarah's age is 60.

Check: Sarah is 60.
The difference between Sarah's age and 44 is 60 - 44 = 16
4 times that difference is 16 * 4 = 64.
Our solution is correct.
