y=3
Consider the second equation. Add 1 and 2 to get 3.
3=x-3
Consider the first equation. Insert the known values of variables into the equation.
x-3=3
Swap sides so that all variable terms are on the left hand side.
x=3+3
Add 3 to both sides.
x=6
Add 3 and 3 to get 6.
z=4-6
Consider the third equation. Insert the known values of variables into the equation.
z=-2
Subtract 6 from 4 to get -2.
y=3 x=6 z=-2
The system is now solved.
