Question

Trevor and Marissa sell T-shirts at the craft fair Marisa has six fewer T-shirts then Trevor and together they have a total of 26 T-shirts how many T-shirts does Trevor have

Answer 1

M + t = 26
m = t - 6

t - 6 + t = 26
2t - 6 = 26
2t = 26 + 6
2t = 32
t = 32/2
t = 16 <== Trevor has 16

m = t - 6
m = 16 - 6
m = 10...and Marissa has 10
