\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: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
