1️⃣ 1/2
2️⃣ -1/2
3️⃣ 3/5
4️⃣ -3/5​

Answer 1

Given:

7m + 4n = 3m + 2n

To Find:

The value of m/n

Solution:

It is given that 7m + 4n = 3m + 2n. The following is the process to find the value of m/n.

According to the given question:

$= > 7m + 4n = 3m - 2n$

$= > 7m - 3m = 2n - 4n$

$= > 4m = - 2n$

$= > \dfrac{m}{n} = \dfrac{ - 2}{4}$

$= > \dfrac{m}{n} = \dfrac{ - 1}{2}$

Hence, the value of m/n = -1/2

Answer 2

Given : 7m + 4n = 3m + 2n

To Find :  m/n

1️⃣ 1/2

2️⃣ -1/2

3️⃣ 3/5

4️⃣ -3/5​

Solution:

7m + 4n = 3m + 2n

=> 7m   - 3m   + 4n - 2n = 0

=>  4m  + 2n  = 0

=> 2m + n = 0

=> 2m/n  + 1  = 0

=> 2 m/n = - 1

=> m/n = - 1/2
