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

Question

Question 1 options:

A)

y = 15

B)

y = 1/5

C)

y = 75

D)

y = –15

Answer 1

Let's solve the equation step by step.

The equation given is:

\[ 80 = 3y + 2y + 4 + 1 \]

First, combine the terms on the right side:

\[ 3y + 2y + 4 + 1 = 5y + 5 \]

Now the equation becomes:

\[ 80 = 5y + 5 \]

Next, subtract 5 from both sides:

\[ 80 - 5 = 5y \]

This simplifies to:

\[ 75 = 5y \]

Now, divide both sides by 5:

\[ y = \frac{75}{5} \]

This simplifies to:

\[ y = 15 \]

So the solution is:

A) y = 15.
