3x=13-7
Consider the first equation. Subtract 7 from both sides.
3x=6
Subtract 7 from 13 to get 6.
x=\frac{6}{3}
Divide both sides by 3.
x=2
Divide 6 by 3 to get 2.
y=2
Consider the second equation. Insert the known values of variables into the equation.
z=2
Consider the third equation. Insert the known values of variables into the equation.
x=2 y=2 z=2
The system is now solved.
