Question

Abdul has 15 shirts to fold. Let n be the number of shirts he would have left to fold after folding f of them. Write an equation relating n to f. Then use this equation to find the number of shirts he would have left to fold after folding 6 of them.

Answer 1

15 - f = n OR f + n = 15

Abdul would have to fold 9 more after folding 6 of them.

Answer 2

n + f = 15

Explanation:

n + f = 15

n + (6) = 15

n = 15 - 6 (opposite side opposite sign)

n = 9
