Question

The difference between Molly and Chase's age is 35. if Molly is 3 times Chase's age plus an additional 10 years,how old are they?

Answer 1

x = Chase's age

3x + 10 = Molly's age

(3x + 10) - x = 35

Solve for x.

Answer 2

Let's consider x = C's age

=> M's age = 3x + 10

therefore, (3x + 10)- x = 35

=> 3x + 10 = 35 + x
=> 2x = 35 -10
=> x = 25/2

=> Molly's age = 12 ½

Now, calculate Chase's age.
