x\times 3=1-1
Consider the second equation. Subtract 1 from both sides.
x\times 3=0
Subtract 1 from 1 to get 0.
x=0
Divide both sides by 3. Zero divided by any non-zero number gives zero.
0+y=-5
Consider the first equation. Insert the known values of variables into the equation.
y=-5
Anything plus zero gives itself.
x=0 y=-5
The system is now solved.
