x+3y+z=60-3 3x+2y=85-6 3x+3y+2z=130-0
Reorder the equations.
x=-3y-z+57
Solve x+3y+z=60-3 for x.
3\left(-3y-z+57\right)+2y=85-6 3\left(-3y-z+57\right)+3y+2z=130-0
Substitute -3y-z+57 for x in the second and third equation.
y=-\frac{3}{7}z+\frac{92}{7} z=-6y+41
Solve these equations for y and z respectively.
z=-6\left(-\frac{3}{7}z+\frac{92}{7}\right)+41
Substitute -\frac{3}{7}z+\frac{92}{7} for y in the equation z=-6y+41.
z=\frac{265}{11}
Solve z=-6\left(-\frac{3}{7}z+\frac{92}{7}\right)+41 for z.
y=-\frac{3}{7}\times \frac{265}{11}+\frac{92}{7}
Substitute \frac{265}{11} for z in the equation y=-\frac{3}{7}z+\frac{92}{7}.
y=\frac{31}{11}
Calculate y from y=-\frac{3}{7}\times \frac{265}{11}+\frac{92}{7}.
x=-3\times \frac{31}{11}-\frac{265}{11}+57
Substitute \frac{31}{11} for y and \frac{265}{11} for z in the equation x=-3y-z+57.
x=\frac{269}{11}
Calculate x from x=-3\times \frac{31}{11}-\frac{265}{11}+57.
x=\frac{269}{11} y=\frac{31}{11} z=\frac{265}{11}
The system is now solved.
