z=25x-0 2=5y a=z
Reorder the equations.
z=25x
Calculate z from z=25x-0.
a=25x
Substitute 25x for z in the equation a=z.
y=\frac{2}{5} x=\frac{1}{25}a
Solve the second equation for y and the third equation for x.
z=25\times \frac{1}{25}a
Substitute \frac{1}{25}a for x in the equation z=25x.
z=a
Calculate z from z=25\times \frac{1}{25}a.
x=\frac{1}{25}a y=\frac{2}{5} z=a
The system is now solved.
