You can put this solution on YOUR website! Use Substitutionto solve each euqations, If the system does not have exactly one solution, state whethter it has no solution or infinitely many solutions.
X-5Y=36
2X+Y=-16
---------
Rearrange:
x = 5y+36
Substitute:
2(5y+36) + y = -16
10y + 72 + y = -16
11y = - 88
y = -8
---------------
Substitute into x = 5y+16
x = 5*-8+16
x = -40+16
x = -24
===============
One solution: (-24,-8)
===============
