z=6x+1 5y=70000 a=z
Reorder the equations.
a=6x+1
Substitute 6x+1 for z in the equation a=z.
y=14000 x=-\frac{1}{6}+\frac{1}{6}a
Solve the second equation for y and the third equation for x.
z=6\left(-\frac{1}{6}+\frac{1}{6}a\right)+1
Substitute -\frac{1}{6}+\frac{1}{6}a for x in the equation z=6x+1.
z=a
Calculate z from z=6\left(-\frac{1}{6}+\frac{1}{6}a\right)+1.
x=-\frac{1}{6}+\frac{1}{6}a y=14000 z=a
The system is now solved.
