Answer:
The answer choice that contains only equations is:
A. 2 + H = 14 and K - 25 = 2
Step-by-step explanation:
A. Both expressions are equations because they have an equal sign and a variable.
B. C-14C-14 is not an equation because it doesn't have an equal sign.
C. Both expressions are equations, but 22-y is not a complete equation (missing an equal sign).
D. Both expressions are equations, but 55= r-1 is not a complete equation (missing an equal sign).
