Answer 4

I don't think that's right... when you subtract them you get 124..

Answer 5

Andre = x
Jen = y

y = x -13
x + y = 137

Solve the system

Answer 6

And then you have double Jen's age. This is basically 2x+13=134=2y-13, and you can solve either or both sides.

Answer 7

Knock I dont know how to solve the system of equations. could you shoe me how?

Answer 9

Sure! There are different ways, I think the faster here is:

Andre = x

Jen = y

1)y = x -13
2)x + y = 137

From 2) y = 137 - x, now substitute y in 1) and 137 - x = x - 13; 150 = 2x;
x = 150 / 2; x = 75 (Andre)

With that value you go to 1) and y = 75 - 13 = 62; y = 62 (Jen)
