z=1\left(x-8\right) y-5=0 a=z
Reorder the equations.
z=x-8
Calculate z from z=1\left(x-8\right).
a=x-8
Substitute x-8 for z in the equation a=z.
y=5 x=8+a
Solve the second equation for y and the third equation for x.
z=8+a-8
Substitute 8+a for x in the equation z=x-8.
z=a
Calculate z from z=8+a-8.
x=8+a y=5 z=a
The system is now solved.
