F=9R-315+75
Use the distributive property to multiply 9 by R-35.
F=9R-240
Add -315 and 75 to get -240.
F=9R-315+75
Use the distributive property to multiply 9 by R-35.
F=9R-240
Add -315 and 75 to get -240.
9R-240=F
Swap sides so that all variable terms are on the left hand side.
9R=F+240
Add 240 to both sides.
\frac{9R}{9}=\frac{F+240}{9}
Divide both sides by 9.
R=\frac{F+240}{9}
Dividing by 9 undoes the multiplication by 9.
R=\frac{F}{9}+\frac{80}{3}
Divide F+240 by 9.
