3x=12-6
Consider the first equation. Subtract 6 from both sides.
3x=6
Subtract 6 from 12 to get 6.
x=\frac{6}{3}
Divide both sides by 3.
x=2
Divide 6 by 3 to get 2.
y=2-9
Consider the second equation. Insert the known values of variables into the equation.
y=-7
Subtract 9 from 2 to get -7.
z=-7
Consider the third equation. Insert the known values of variables into the equation.
x=2 y=-7 z=-7
The system is now solved.
