y-9=\frac{6}{7}x+6
Use the distributive property to multiply \frac{6}{7} by x+7.
\frac{6}{7}x+6=y-9
Swap sides so that all variable terms are on the left hand side.
\frac{6}{7}x=y-9-6
Subtract 6 from both sides.
\frac{6}{7}x=y-15
Subtract 6 from -9 to get -15.
\frac{\frac{6}{7}x}{\frac{6}{7}}=\frac{y-15}{\frac{6}{7}}
Divide both sides of the equation by \frac{6}{7}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y-15}{\frac{6}{7}}
Dividing by \frac{6}{7} undoes the multiplication by \frac{6}{7}.
x=\frac{7y}{6}-\frac{35}{2}
Divide y-15 by \frac{6}{7} by multiplying y-15 by the reciprocal of \frac{6}{7}.
y-9=\frac{6}{7}x+6
Use the distributive property to multiply \frac{6}{7} by x+7.
y=\frac{6}{7}x+6+9
Add 9 to both sides.
y=\frac{6}{7}x+15
Add 6 and 9 to get 15.
