z=x 3x+2y=10 a=z
Reorder the equations.
a=x
Substitute x for z in the equation a=z.
y=-\frac{3}{2}x+5 x=a
Solve the second equation for y and the third equation for x.
y=-\frac{3}{2}a+5
Substitute a for x in the equation y=-\frac{3}{2}x+5.
z=a
Substitute a for x in the equation z=x.
x=a y=-\frac{3}{2}a+5 z=a
The system is now solved.
