# How do you solve N-1/5=7/20?

Dec 5, 2016

$N = \frac{11}{20}$

#### Explanation:

First, isolate the $N$ term on one side of the equation and the fractions on the other side of the equation while keeping the equation balanced:

$N - \frac{1}{5} + \frac{1}{5} = \frac{7}{20} + \frac{1}{5}$

$N - 0 = \frac{7}{20} + \frac{1}{5}$

$N = \frac{7}{20} + \frac{1}{5}$

Next we need to get the constants over a common denominator, in this case 20, by multiplying by the correct form of $1$:

$N = \frac{7}{20} + \left(\frac{1}{5} \cdot \frac{4}{4}\right)$

$N = \frac{7}{20} + \frac{4}{20}$

$N = \frac{11}{20}$
