Question

solve and verify this ​

Answer 1

Answer:

$\huge\underbrace\mathfrak\pink{answer:-}$

(3x-1)/5-x/7=3

(21x-7-5x)/35=3

16x-7=105

16x=112

x=112/16

x=7

verification

(3x-1)/5 -x/7=3

3×3-1/5 -3/7 =3

8/5 - 3/7=3

3=3

Answer 2

$\begin{gathered}\frac{3x - 1}{5} - \frac{x}{7} = 3 \\ \\ = > \frac{7(3x - 1) - 5x}{35} = 3 \\ \\ = > \frac{21x - 7 - 5x}{35} = 3 \\ \\ = > 16x - 7 = 105 \\ \\ = > 16x = 112 \\ \\ = > x = \frac{112}{16} = 7\end{gathered}$

Verification:-

$\begin{gathered}= > \frac{3(7) - 1}{5} - \frac{7}{7} = 3 \\ \\ = > \frac{21 - 1}{5} - 1 = 3 \\ \\ = > \frac{20}{5} - 1 = 3 \\ \\ = > 4 - 1 = 3 \\ \\ = > 3 = 3\end{gathered}$
