5x+x=120
Consider the first equation. Combine 2x and 3x to get 5x.
6x=120
Combine 5x and x to get 6x.
x=\frac{120}{6}
Divide both sides by 6.
x=20
Divide 120 by 6 to get 20.
y=20
Consider the second equation. Insert the known values of variables into the equation.
z=20
Consider the third equation. Insert the known values of variables into the equation.
x=20 y=20 z=20
The system is now solved.
