-x=7-38
Consider the first equation. Subtract 38 from both sides.
-x=-31
Subtract 38 from 7 to get -31.
x=\frac{-31}{-1}
Divide both sides by -1.
x=31
Fraction \frac{-31}{-1} can be simplified to 31 by removing the negative sign from both the numerator and the denominator.
x=31 y=1 z=1
The system is now solved.
