Question

Solve this equation: 80 = 3y + 2y +4+1.

A. y = 16
B.y = 15
C. y = 75
D. y=-15

Answer 1

B = 15

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.

Answer 2

The answer is B because it is 80=5y+5 and if you subtract 5 it’s 75=5y and if you divide by 5 it’s +16
