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