-x=-30
Consider the first equation. Subtract 30 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-30}{-1}
Divide both sides by -1.
x=30
Fraction \frac{-30}{-1} can be simplified to 30 by removing the negative sign from both the numerator and the denominator.
x=30 y=50 z=50 a=50 b=50
The system is now solved.
