5.5B=28-4R
Subtract 4R from both sides.
\frac{5.5B}{5.5}=\frac{28-4R}{5.5}
Divide both sides of the equation by 5.5, which is the same as multiplying both sides by the reciprocal of the fraction.
B=\frac{28-4R}{5.5}
Dividing by 5.5 undoes the multiplication by 5.5.
B=\frac{56-8R}{11}
Divide 28-4R by 5.5 by multiplying 28-4R by the reciprocal of 5.5.
4R=28-5.5B
Subtract 5.5B from both sides.
4R=-\frac{11B}{2}+28
The equation is in standard form.
\frac{4R}{4}=\frac{-\frac{11B}{2}+28}{4}
Divide both sides by 4.
R=\frac{-\frac{11B}{2}+28}{4}
Dividing by 4 undoes the multiplication by 4.
R=-\frac{11B}{8}+7
Divide 28-\frac{11B}{2} by 4.
