Choose the equation that models the problem.

Luisa won 17 tennis matches last summer. She played a total of 26 matches. How many matches did she lose overall?

Let l represent the number of games that Luisa lost.

A.
l – 17 = 26

B.
l + 26 = 17

C.
17l = 26

D.
l + 17 = 26

Answer 1

Assuming that a tennis match can only be won and lost, Luisa's games can be expressed as follows:\[\text{Games Won}+\text{Games Lost}=\text{Total Games}.\]You are already told that \(\text{Games Won}=17\) and \(\text{Total Games}=26\).

Answer 2

All that you now have to do is substitute, relabel and rearrange.
