1+1\times 4=\frac{4b+16}{1}
Divide 1 by \frac{1}{4} by multiplying 1 by the reciprocal of \frac{1}{4}.
1+4=\frac{4b+16}{1}
Multiply 1 and 4 to get 4.
5=\frac{4b+16}{1}
Add 1 and 4 to get 5.
5=4b+16
Anything divided by one gives itself.
4b+16=5
Swap sides so that all variable terms are on the left hand side.
4b=5-16
Subtract 16 from both sides.
4b=-11
Subtract 16 from 5 to get -11.
b=\frac{-11}{4}
Divide both sides by 4.
b=-\frac{11}{4}
Fraction \frac{-11}{4} can be rewritten as -\frac{11}{4} by extracting the negative sign.
