Question

This year, the Newville Tigers won six games more than the Wilton Panthers won. The Tigers won 22 games. Which equation cannot be used to find the number of games the Panthers won?

A b+6=22
B. 22 - b = 6
C. 22 = 6 + b
D. b - 6 = 22​

Answer 1

The ones that can be used are (B and A)

The ones that cannot be used are (C and D)

Explanation:

Because the panthers got 6 less and the tigers got 22…

b+6 would make 22 (panthers plus 6 makes tigers)

22-b would also be 6 because 6+b makes 22, so subtracting b from 22 makes 6
