3y=1-4
Consider the first equation. Subtract 4 from both sides.
3y=-3
Subtract 4 from 1 to get -3.
y=\frac{-3}{3}
Divide both sides by 3.
y=-1
Divide -3 by 3 to get -1.
z=-1
Consider the second equation. Insert the known values of variables into the equation.
a=-1
Consider the third equation. Insert the known values of variables into the equation.
y=-1 z=-1 a=-1
The system is now solved.
