  • option 3 is correct

\large\huge\green{\sf{Explanation:-}}

➡7m - 2n = 5m + 3n \\ ➡7m  - 5m  = 3n + 2n \\ ➡ 2m = 5n \\ ➡m =  \frac{5n}{2}    \\ now _{ - } \\  \frac{4m+3n}{4m - 3n}   \\ \\  put \: value \: of \:  :  -  \\   = \frac{4 \times  ( \frac{5n}{2} )+ 3n}{4 \times  ( \frac{5n}{2} ) -  3n}  \\    = \frac{\frac{20n}{2}  + 3n}{\frac{20n}{2}   -  3n} =    \frac{\frac{20 + 6n {}^{} }{2} }{\frac{20  - 6n {}^{} }{2} }  \\  =  \frac{26n}{14n}  =  \frac{13}{7}

Given:

If 7m-2n=5m+3n

To Find:

then (4m+3n)/(4m-3n)=?

1️⃣ 5/2 2️⃣ 10/3 3️⃣ 13/7 4️⃣ 26/7

Solution:

It is given that 7m-2n=5m+3n, then we can find the value of m in terms of n then we will substitute the same in the To Find equation,

Finding the value of m,

7m-2n=5m+3n

2m=5n

m=2.5n

Now substituting the value of m in the equation to find the value, which goes as,

=\frac{4m+3n}{4m-3n}

Let this be equal to x, so will need to find the value of x,

x=\frac{4m+3n}{4m-3n} \\=\frac{10n+3n}{10n-3n}\\=\frac{13n}{7n}\\=\frac{13}{7}

So the value of x is 13/7

Hence, the correct option is (3).
