Answer:

a. Jared and Ali

Explanation:

b. Molly make mistake when he/she divide all equation by 4 but left the 8x remain 8x, it should be 2x.

Mark make mistake in changing the sign whitout changing side/ passing trough equal sign. FYI, + can be - and also - can be + if they move to the other side

i.e.

2 + 3 = 5

2 = 5 - 3
