Answer:
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.
