-2x - 4 + 5y = 8 solve?

Step-by-step explanation:

You have ONE equation here in TWO unkowns.  You can solve for either x or y but not both.  Only if you have a system of TWO equations can you find the values of x and y that satisfy both equations.

-2x - 4 + 5y = 8 is to be solved for y:

Add 4 to both sides to combine the constant terms:

-2x + 5y = 12

To solve for y, add 2x to both sides, obtaining:

5y = 2x + 12

and then divide all three terms by 5:

y = (2/5)x + 12/5

-2x - 4 + 5y = 8 can also be solved for x if desired.
