y=-\frac{2}{5}+8
Consider the first equation. Fraction \frac{-2}{5} can be rewritten as -\frac{2}{5} by extracting the negative sign.
y=\frac{38}{5}
Add -\frac{2}{5} and 8 to get \frac{38}{5}.
z=12
Consider the second equation. Multiply 3 and 4 to get 12.
a=12
Consider the third equation. Insert the known values of variables into the equation.
y=\frac{38}{5} z=12 a=12
The system is now solved.
