4y-2y=-4
Consider the first equation. Subtract 2y from both sides.
2y=-4
Combine 4y and -2y to get 2y.
y=\frac{-4}{2}
Divide both sides by 2.
y=-2
Divide -4 by 2 to get -2.
z=-2
Consider the second equation. Insert the known values of variables into the equation.
a=-2
Consider the third equation. Insert the known values of variables into the equation.
y=-2 z=-2 a=-2
The system is now solved.
