Trevor and marissa together have 26 t-shirts to sell. If marissa has 6 fewer t-shirts than trevor find how many t-shirts trevor has. Identify the if-then moves in your solution

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.
