\frac{2}{7}y=\frac{1}{17}z+10-20
Subtract 20 from both sides.
\frac{2}{7}y=\frac{1}{17}z-10
Subtract 20 from 10 to get -10.
\frac{2}{7}y=\frac{z}{17}-10
The equation is in standard form.
\frac{\frac{2}{7}y}{\frac{2}{7}}=\frac{\frac{z}{17}-10}{\frac{2}{7}}
Divide both sides of the equation by \frac{2}{7}, which is the same as multiplying both sides by the reciprocal of the fraction.
y=\frac{\frac{z}{17}-10}{\frac{2}{7}}
Dividing by \frac{2}{7} undoes the multiplication by \frac{2}{7}.
y=\frac{7z}{34}-35
Divide \frac{z}{17}-10 by \frac{2}{7} by multiplying \frac{z}{17}-10 by the reciprocal of \frac{2}{7}.
\frac{1}{17}z+10=\frac{2}{7}y+20
Swap sides so that all variable terms are on the left hand side.
\frac{1}{17}z=\frac{2}{7}y+20-10
Subtract 10 from both sides.
\frac{1}{17}z=\frac{2}{7}y+10
Subtract 10 from 20 to get 10.
\frac{1}{17}z=\frac{2y}{7}+10
The equation is in standard form.
\frac{\frac{1}{17}z}{\frac{1}{17}}=\frac{\frac{2y}{7}+10}{\frac{1}{17}}
Multiply both sides by 17.
z=\frac{\frac{2y}{7}+10}{\frac{1}{17}}
Dividing by \frac{1}{17} undoes the multiplication by \frac{1}{17}.
z=\frac{34y}{7}+170
Divide \frac{2y}{7}+10 by \frac{1}{17} by multiplying \frac{2y}{7}+10 by the reciprocal of \frac{1}{17}.
