x=-3
Consider the first equation. Divide both sides by -1.
y=4-\left(-3\right)
Consider the second equation. Insert the known values of variables into the equation.
y=4+3
Multiply -1 and -3 to get 3.
y=7
Add 4 and 3 to get 7.
z=7
Consider the third equation. Insert the known values of variables into the equation.
x=-3 y=7 z=7
The system is now solved.
