9=-4x+7
Consider the first equation. Insert the known values of variables into the equation.
-4x+7=9
Swap sides so that all variable terms are on the left hand side.
-4x=9-7
Subtract 7 from both sides.
-4x=2
Subtract 7 from 9 to get 2.
x=\frac{2}{-4}
Divide both sides by -4.
x=-\frac{1}{2}
Reduce the fraction \frac{2}{-4} to lowest terms by extracting and canceling out 2.
y=9 x=-\frac{1}{2}
The system is now solved.
