8x - 5y = -25
Subtract 8x from both sides
-5y = -25 - 8x
Divide both sides by -5
y = 5 + 8/5x
y = 8/5x + 5
-2x - 5y = -25
Add 2x to both sides
-5y = 2x - 25
Divide both sides by -5
y = -2/5x + 5
These are the equations, and at x = 0, (0, 5) these coordinates are where these equations intersect. The solution is (0, 5) or x = 0 for both of these.
