Question

What would y equal in this equation?
3 + 4/1y = 5x + 2

Answer 1

Explanation:

Since you can't directly solve for
`y` 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}}`

• 
  `y=(1)/(2)`
• 
  `x=-2`

_____________________________________

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.

Have a good day :) !
