Question

Together, Lee and Joanna have 19 computer games. Joanna has 3 more games than Lee. Write and solve an equation to find the number of games each friend had.

Answer 1

L=8 and J=11

Explanation:

If Lee is L and Joanna is J we get: L+J=19.

And since Joanna has 3 more than Lee we get: J=L+3

When we substitute J for L+3 we get: 2L+3=19

When we solve we get: L=8

Finally, since J=L+3 we get: J=11
