Explanation:

Since you can't directly solve for
in this question, we will use substitution to solve for

${\large{\boxed{\mathbb{QUESTION}}}$

What would y equal in this equation?

$\begin{bmatrix}3+(4)/(1)y=5\\ x+2=0\end{bmatrix}$

${\large{\boxed{\mathbb{SOLVE\:FOR\:Y}}}$

3+(4)/(1)y=5

First, we will subtract 3 from both sides of the equation

(4)/(1)y=2

Simplify

{4}y=2

Divide both sides by 4

y=(1)/(2)

${\large{\boxed{\mathbb{SOLVE\:FOR\:X}}}$

x+2=0

subtract 2 to both sides

x=-2

${\large{\boxed{\mathbb{ANSWER}}$

_____________________________________

If we didn't use the method with substitution and had our equation being

3+(4)/(1y)=5x+2

our answer would've been

y=(-4)/(-5x+1) , I highly doubt this would be the right answer.
