x=3-7
Consider the first equation. Subtract 7 from both sides.
x=-4
Subtract 7 from 3 to get -4.
y=-4
Consider the second equation. Insert the known values of variables into the equation.
z=-4
Consider the third equation. Insert the known values of variables into the equation.
x=-4 y=-4 z=-4
The system is now solved.
