-x=-15-3
Consider the first equation. Subtract 3 from both sides.
-x=-18
Subtract 3 from -15 to get -18.
x=\frac{-18}{-1}
Divide both sides by -1.
x=18
Fraction \frac{-18}{-1} can be simplified to 18 by removing the negative sign from both the numerator and the denominator.
x=18 y=42 z=42
The system is now solved.
