The equation 3y + 7 = 22 is solved by subtracting 7 from both sides and then dividing by 3, yielding y = 5. So, the answer is A. 5.
To solve the equation 3y + 7 = 22 for y, we can isolate y by subtracting 7 from both sides of the equation and then dividing by 3:
- 3y + 7 - 7 = 22 - 7
- 3y = 15
- y = 5
Therefore, the correct answer is A. 5.

A. 5
B. 3
C. 4
D. 6
