Question

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

Answer 1

system of equations

Answer 2

Just like in the previous question. Isolate any variable in either equation. It would be easier to isolate the y variable in the first equation.

4x - y = 8 => when you solve it for y, you get => y=4x-8

Now plug in "y=4x-8" into the second equation

-8x + 2y = -5 Plug in "4x-8" where there is currently a Y.


-8x+2(4x-8)=-5. Now simpllify this equation.

Answer 3

But the problem you may encounter is that you won't get a solution. This is because these two lines are parallel, which means that they don't intersect. There would be no solution.
