Answer:

The answer to your question is Marissa = 6, Trevor = 16

Step-by-step explanation:

Data

total number of t-shirts = 26

Marissa has 6 fewer than trevor

Process

1.- Write equations to solve this problem

Marissa = m

Trevor = t

                      m + t = 26                Equation l

                       m = t - 6                  Equation ll

- Substitute equation ll in equation l

                   (t - 6) + t = 26

-Simplify

                    t - 6 + t = 26

                    2t = 26 + 6

                    2t = 32

                      t = 32/2

                      t = 16

- Find m

                    m = 16 - 6

                    m = 10

-Conclusion

Trevor has 16 t-shirts and Marissa has 10 t-shirts.
