7x=18+2
Consider the first equation. Add 2 to both sides.
7x=20
Add 18 and 2 to get 20.
x=\frac{20}{7}
Divide both sides by 7.
y=\frac{20}{7}
Consider the second equation. Insert the known values of variables into the equation.
z=\frac{20}{7}
Consider the third equation. Insert the known values of variables into the equation.
x=\frac{20}{7} y=\frac{20}{7} z=\frac{20}{7}
The system is now solved.
