6x=72
Consider the first equation. Combine 2x and 4x to get 6x.
x=\frac{72}{6}
Divide both sides by 6.
x=12
Divide 72 by 6 to get 12.
y=12
Consider the second equation. Insert the known values of variables into the equation.
z=12
Consider the third equation. Insert the known values of variables into the equation.
x=12 y=12 z=12
The system is now solved.
