Math Problem x2

Question

Noah is 144 years old. Megan is 40 years old. How many years until Noah's age is 3 times Megan's age?

Answer 1

144+x = 3(40+x) = 120 + 3x

2x = 24

x = 12 years when Noah is 3 times Megan's age

156 = 3(52)

(or if this is a trick question, Noah is already more than 3 times Megan's age, but in 12 years he'll be exactly 3 times her age)
