Which are equations? CHECK all that apply. X+3=12

Z/7+1

25-q

6g=18

2/3m

P/3.5=2.25

9=100-f

K divided by 5.8

X + 3 = 12

6g = 18

P/3.5 = 2.25

9 = 100 - f

Step-by-step explanation:

Equations have equal signs.

Expressions do not.

Therefore, any expression with an equal sign is an equation, making it one of the correct answers.
