x=5-5
Consider the first equation. Subtract 5 from both sides.
x=0
Subtract 5 from 5 to get 0.
2\times 0-y=1
Consider the second equation. Insert the known values of variables into the equation.
0-y=1
Multiply 2 and 0 to get 0.
-y=1
Anything plus zero gives itself.
y=-1
Divide both sides by -1.
x=0 y=-1
The system is now solved.
