Question

solve the following linear equations.
n/2-3n/4+5n/6=21​

Answer 1

Answer:

n=36

Step-by-step explanation:

n/2-3n/4+5n/6=21

taking LCM

(6n-9n+10n)/12=21

7n=252

n=36

Answer 2

Step-by-step explanation:

L. C. M of 2,4 & 6=12

6n-9n+10n/12=21

7n/12=21

21×12=7n

n = 21×12/7

=36

Hence, n=36
