welcome student this is part five in
0:02
series of linear equations we will be
0:04
seeing some complex linear equations
0:07
question number one solve the linear
0:08
equation n / 2 - 3 n / 4 + 5 n / 6 = 21
0:16
so looking at the equation we can see
0:18
that we are having both the numerator
0:21
and denominator in the equation so the
0:22
strategy to solve this question would be
0:24
to First Take the LCM of the
0:26
denominators so here the denominators
0:28
are 2 4 and 6 so calculating the LCM
0:32
we'll get 12 now we need to multiply 12
0:35
on both the side so multiplying 12 on
0:38
both side we get 6 N - 3 n + 10 n = 252
0:43
now simplifying the same terms we get 7
0:46
n = 252 now dividing by 7 on both the
0:50
side we get n = 32 so that way we can
0:53
resolve these type of questions let's
0:55
take a look at another question the
0:57
question number two is x + 7- - 8X / 3 =
1:02
17 / 6 - 5x / 2 now this question has
1:08
both the uh things like first the this
1:11
is having both the numerator and
1:13
denominator and then the left hand side
1:15
and right hand sides are having the
1:16
constant and the variables so first
1:19
strategy would be to First find the LCM
1:21
of denominators so denominators here are
1:23
two 6 and 3 so taking LCM we get six so
1:27
we need to multiply six on both the side
1:29
so we get 6X + 42 - 16x = 17 - 15x now
1:35
we need to get the same terms on the
1:38
similar side so transposing 15x to the
1:40
right hand side and 42 to the left hand
1:42
side we get 6x - 16x + 15x = 17 - 42
1:48
simplifying that 5x = -25 dividing by 5
1:53
on both the side we get X = -5 for more
