Question

(1/n+80) + (1/n+20). Find n.

Answer 1

Answer:

Step-by-step explanation:

{(1/n)+80}+{(1/n)+20}

={(1+80n)/n}+{(1+20n)/n}

=(1+80n+1+20n)/n

=(100n+2)/n

=100+(2/n)

Answer 2

open both brackets

1/n + 80 +1/n + 20

next

like term = 1/n +1/n +80 +20

we solve. l.c. m of n, n is n

1+1/n +80+20

2/n + 100

l.c. m = n

2×1+100n/n

2+100n / n

take common 2(1+50n)/n
