Answer:

12 years

Explanation:

Represent the mother's age by m and the son's by 4. Currently m = 36 years old.

In x years the mother will be three times as old as her son:

mother: 36 + x years old

son: 4 + x years old

The pertinent equation to solve is:

36 + x = 3(4 + x)

Performing the multiplication, we get:

36 + x = 12 + 3x, or

24 = 2x. Then x = 12.

Check: In 12 years, will the mother's age be 3 times the son's age?

Does 36 + 12 = 3(4 + 12)?

Does 48 = 48? YES

The mother will be 3 times as old as her son in 12 years from now.
