Answer:
let me explain how you do this:
Explanation:
first, you write your equation down:
-x + 5y = 8
next, group everything out seperately so you can know what to do in this problem, like grouping out each variable and number you see. then, figure out if the solution is simplified down to the last number. if so, if there is two variables that aren't the same, try and figure out a way to solve this equation with these two different variables. figure out if you have to multiply, subtract, add, or divide.
