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