4.3+2n=8.7
Swap sides so that all variable terms are on the left hand side.
2n=8.7-4.3
Subtract 4.3 from both sides.
2n=4.4
Subtract 4.3 from 8.7 to get 4.4.
n=\frac{4.4}{2}
Divide both sides by 2.
n=\frac{44}{20}
Expand \frac{4.4}{2} by multiplying both numerator and the denominator by 10.
n=\frac{11}{5}
Reduce the fraction \frac{44}{20} to lowest terms by extracting and canceling out 4.
