Answer 2

Answer:

Step-by-step explanation:

$\frac{15}{8} - 7x = 9$

Move numbers on one side and x on one side.

So move 15/8 on R.H.S

Note : Sign changes as we move numbers or variable to other side

$-7x = 9 - \frac{15}{8}$

$-7x = \frac{72 - 15}{8}\\-7x = \frac{57}{8}\\-7 * x = \frac{57}{8}\\\\x = \frac{-57}{8*7}\\\\x = \frac{-57}{56}$
