If Jody had $3 more she would have twice as much as Lars together they have $60

If Jody had $3 more she would have twice as much as Lars together they have $60.

Let j be Jody's money and l be Lars's money. We have two equations:

1. j + l = 60
2. j + 3 = 2l

Rearrange (2) to solve for j by subtracting 3
j = 2l - 3

Now substitute this into (1)
(2l - 3) + l = 60

Combine like terms
3l - 3 = 60

Enter this into our equation calculator, and we get:
l = 21

Now plug l = 21 into our rearranged equation above:
j = 2(21) - 3
j = 42 - 3
j = 39
