Question

3x-1/5- x/7 =3. pls answer me as soon as possible​

Answer 1

Answer:

$3x - \frac{1}{5} - \frac{x}{7} = 3 \\ \frac{75x - 7 - 5 x}{35} = 3 \\ \frac{70x - 7}{35} = 3 \\ \frac{7(10x - 1)}{35} = 3 \\ \frac{10x - 1}{5} = 3 \\ 10x - 1 = 15 \\ 10x = 15 - 1 \\ 10x = 14 \\ x = \frac{14}{10} \\ x = \frac{7}{5}$
