1) Plug 5 into all the spots for x. See if it makes the equation true.

A. 2+5 = 3  Nope

B. 3(5) = 15 Yep

C. 5/2 = 10 Nuh-uh

D. 5-7 = 12  Nah

<u>B is the answer :)</u>

I'm not sure if you need the answer to #2 but I'll answer it anyway. :)

2) An equation has to have a solution. This means it has an equal sign. C is the only one that has an equal sign.

<u>C is the answer :)</u>
