8A+98=CB
Multiply 2 and 4 to get 8.
8A=CB-98
Subtract 98 from both sides.
8A=BC-98
The equation is in standard form.
\frac{8A}{8}=\frac{BC-98}{8}
Divide both sides by 8.
A=\frac{BC-98}{8}
Dividing by 8 undoes the multiplication by 8.
A=\frac{BC}{8}-\frac{49}{4}
Divide CB-98 by 8.
8A+98=CB
Multiply 2 and 4 to get 8.
CB=8A+98
Swap sides so that all variable terms are on the left hand side.
\frac{CB}{C}=\frac{8A+98}{C}
Divide both sides by C.
B=\frac{8A+98}{C}
Dividing by C undoes the multiplication by C.
B=\frac{2\left(4A+49\right)}{C}
Divide 8A+98 by C.
