#N = 11/20#

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 - 1/5 + 1/5 = 7/20 + 1/5#

#N - 0 = 7/20 + 1/5#

#N = 7/20 + 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 = 7/20 + (1/5 * 4/4)#

#N = 7/20 + 4/20#

#N = 11/20#
