Question

If l/m-p=2n/m, find the value of n when l=4, m=3 and p=-7​

Answer 1

$\LARGE{\mathfrak{\underline{\underline{Question:-}}}}$

If $\dfrac{l}{m}$ - p = $\dfrac{2n}{m}$, find the value of n when l = 4,m = 3 and p = -7

$\LARGE{\mathfrak{\underline{\underline{Solution :-}}}}$

$\dfrac{l}{m}$ - p = $\dfrac{2n}{m}$

$\implies \dfrac{4}{3}-(-7)$$=\dfrac{2n}{3}$

$\implies \dfrac{4}{3}+7$$=\dfrac{2n}{3}$

$\implies \dfrac{4 + 7\times 3}{3}$$=\dfrac{2n}{3}$

$\implies \dfrac{4+21}{3}=$$\dfrac{2n}{3}$

$\implies \dfrac{25}{3}$$=\dfrac{2n}{3}$

$\implies 25=\dfrac{2n}{3}\times 3$

$\implies 25 = 2n$

$\implies \dfrac{25}{2} = n$

$\implies 12 \dfrac{1}{2} = n$

Or,

$12.5 = n$

Therefore,

Value of n = $12 \dfrac{1}{2}$

Or,

$12.5$

Answer 2

Answer:12.5

Step-by-step explanation:

GIVEN THAT,

= I/M-P=2N/M----     I=4

                                 M=3

                                P= -7

=Sol-

= 4/3-(-7)=2n/3

= 4/3+7=2n/3

= 4+21/3=2n/3

= 25/3=2n/3

= 25/3*3=2n

= 75/3=2n

= 25=2n

= n=12.5

Hence the answer is 12.5
