-x=5-12
Consider the first equation. Subtract 12 from both sides.
-x=-7
Subtract 12 from 5 to get -7.
x=\frac{-7}{-1}
Divide both sides by -1.
x=7
Fraction \frac{-7}{-1} can be simplified to 7 by removing the negative sign from both the numerator and the denominator.
x=7 y=7 z=7 a=7 b=7
The system is now solved.
