Answer 1

[AI-generated answer — Bot GPT 3.5]

To solve this system of equations, we can first solve the first equation for x in terms of y:

x = 15 - 3y

Next, substitute this expression for x into the second equation:
3(15 - 3y) + 2y = 10
45 - 9y + 2y = 10
45 - 7y = 10
-7y = -35
y = 5

Therefore, y = 5.
