x+6y=4+2x z=y a=z
Multiply each equation by the least common multiple of denominators in it. Simplify.
z=y x+6y=4+2x a=z
Reorder the equations.
a=y
Substitute y for z in the equation a=z.
x=6y-4 y=a
Solve the second equation for x and the third equation for y.
x=6a-4
Substitute a for y in the equation x=6y-4.
z=a
Substitute a for y in the equation z=y.
x=6a-4 y=a z=a
The system is now solved.
