2x=27-7
Consider the first equation. Subtract 7 from both sides.
2x=20
Subtract 7 from 27 to get 20.
x=\frac{20}{2}
Divide both sides by 2.
x=10
Divide 20 by 2 to get 10.
y=10
Consider the second equation. Insert the known values of variables into the equation.
z=10
Consider the third equation. Insert the known values of variables into the equation.
x=10 y=10 z=10
The system is now solved.
