Question

What would be the equation and how can I solve it

Answer 1

If alonzo is x then the equation is

x + (x +3) + 2(x + 3) = 57

Which equals

x + x + 3 + 2x + 6 = 57
4x + 9 = 57
4x = 48
x = 12

This means alonzo is 12 years old and alexis is 3 years older so alexis is 15 years old

Answer = 15 years old

Answer 2

I did the math and got 15 so heor she is right and i am right and now you will be right:)
