Question

n/5 - 5/7 = 2/3 Solve the equation

Answer 1

(7N - 25) / 35 = 2/3 
3(7N - 25) = 35 * 2 
21N - 75 = 70 
21N = 70 +75 
21N = 145
N = 145/21
N = 6.90

Answer 2

Answer:

$n = \frac{145}{21}$

Step-by-step explanation:

Given equation is

$\frac{n}{5} - \frac{5}{7} = \frac{2}{3}$

$\frac{n}{5} = \frac{2}{3} + \frac{5}{7}$

$\frac{n}{5} = \frac{14\ +\ 15}{21}$

$\frac{n}{5} = \frac{29}{21}$

$n = \frac{29}{21} \times5$

$n = \frac{145}{21} (Answer)$
