Question

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

Answer 1

Combine like terms:


`3y + 2y = 5y`

`4 + 1 = 5`

`80 = 5y + 5`

Subtract 5 from both sides:


`75 = 5y`

Divide both sides by 5:


`15 = y`

The value of y is 15.

Answer 2

Standard form:

−5y + 75 = 0
Factorization:

−5(y − 15) = 0
Solutions:

y = 755 = 15

Hope this helped!
