4=x
Consider the first equation. Add 1 and 3 to get 4.
x=4
Swap sides so that all variable terms are on the left hand side.
4+4=y
Consider the second equation. Insert the known values of variables into the equation.
8=y
Add 4 and 4 to get 8.
y=8
Swap sides so that all variable terms are on the left hand side.
8+4=z
Consider the third equation. Insert the known values of variables into the equation.
12=z
Add 8 and 4 to get 12.
z=12
Swap sides so that all variable terms are on the left hand side.
x=4 y=8 z=12
The system is now solved.
