x=7-4
Consider the first equation. Subtract 4 from both sides.
x=3
Subtract 4 from 7 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.
