Question

Which ones it’s multiple choice btw.

Answer 1

A: 1, 2 B: 4

For A, it is 1 because it divides both by 7 and puts it on the outside. It is 2 because that is just the parts apart from each other and using pemdas it is the same.

For B, it is 4 because if you add/subtract everything, that is what it equals.
