Question

) Solve: {2n-(7-5n)}/{9n-(4-2n)}=3/7​

Answer 1

Answer:

$\frac{37}{16}$

Step-by-step explanation:

$\frac{2n - (7 - 5n)}{9n - (4 - 2n)} = \frac{3}{7}$

$=> \frac{2n - 7 + 5n}{9n - 4 + 2n} = \frac{3}{7}$

$=> \frac{7n - 7}{11n - 4} = \frac{3}{7}$

$= > 33n - 12 = 49n - 49$

=> 49n - 33n = 49 - 12

=> 16n = 37

=> n = 37/16
