7x=22+11
Consider the first equation. Add 11 to both sides.
7x=33
Add 22 and 11 to get 33.
x=\frac{33}{7}
Divide both sides by 7.
y=5\times \frac{33}{7}+8
Consider the second equation. Insert the known values of variables into the equation.
y=\frac{165}{7}+8
Multiply 5 and \frac{33}{7} to get \frac{165}{7}.
y=\frac{221}{7}
Add \frac{165}{7} and 8 to get \frac{221}{7}.
z=\frac{221}{7}
Consider the third equation. Insert the known values of variables into the equation.
x=\frac{33}{7} y=\frac{221}{7} z=\frac{221}{7}
The system is now solved.
