Solve for x_2
x_{2}=10\left(z-3\right)
Solve for z
z=\frac{x_{2}}{10}+3

x_{2}\times 0.1=z-3
Subtract 3 from both sides.
0.1x_{2}=z-3
The equation is in standard form.
\frac{0.1x_{2}}{0.1}=\frac{z-3}{0.1}
Multiply both sides by 10.
x_{2}=\frac{z-3}{0.1}
Dividing by 0.1 undoes the multiplication by 0.1.
x_{2}=10z-30
Divide z-3 by 0.1 by multiplying z-3 by the reciprocal of 0.1.
z=x_{2}\times 0.1+3
Swap sides so that all variable terms are on the left hand side.
