Question

solve the following equations
$\frac{n}{5} - \frac{5}{7} = \frac{2}{3}$
​

Answer 1

Step-by-step explanation:

$\frac{ n}{5} - \frac{5}{7} = \frac{2}{3} \\ = \frac{n}{5} = \frac{14 + 15}{21} \\ \frac{n}{5} = \frac{29}{21} \\ = n = \frac{145}{21}$

Answer 2

Answer:

7n-25=70/3

21n-75=70

21n=145

n=6.9
