2x+2y-2y=0
Consider the first equation. Subtract 2y from both sides.
2x=0
Combine 2y and -2y to get 0.
x=0
Divide both sides by 2. Zero divided by any non-zero number gives zero.
0+y=12
Consider the second equation. Insert the known values of variables into the equation.
y=12
Anything plus zero gives itself.
x=0 y=12
The system is now solved.
