Solve this equation: 80 = 3y + 2y +4+1.
A. y = 16
B. y = 15
C. y = 75
D. y=-15

B = 15

Step-by-step explanation:

We can immediately take out y since there are no negatives in the picture.

3y + 2y = 5y so we are going to divide by 5 at one point, so it can't be C.

That leaves us with A and B, eventually the equation is 75/5, which equals 15 and not 16, so the answer is B.
