-9y=-63
Consider the second equation. Combine y and -y to get 0.
y=\frac{-63}{-9}
Divide both sides by -9.
y=7
Divide -63 by -9 to get 7.
-19x=7
Consider the first equation. Insert the known values of variables into the equation.
x=-\frac{7}{19}
Divide both sides by -19.
x=-\frac{7}{19} y=7
The system is now solved.
