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
