Consider the system of the equation

\begin{align*} 5x + y &= 31, \\ -3x + 4y &= -37. \end{align*}

Solve the first equation for y in terms of x

Enter your answer in the form "$y = \dotsb.$"

The question does not ask for the value of y. It is asking for the first equation solved for y .

5x + y = 31

Subtract 5x from both sides of the equation to get

y = 31 - 5x

This is the first equation solved for y
