1+x=1
Consider the first equation. Subtract 4 from 5 to get 1.
x=1-1
Subtract 1 from both sides.
x=0
Subtract 1 from 1 to get 0.
y=0-4
Consider the second equation. Insert the known values of variables into the equation.
y=-4
Subtract 4 from 0 to get -4.
z=-4
Consider the third equation. Insert the known values of variables into the equation.
x=0 y=-4 z=-4
The system is now solved.
