subtract from both sides
multiply both sides
divide both sides

Explanation:

Step1: Add 8x to both sides

$9x + 7 + 8x = 1 - 8x + 8x$
$17x + 7 = 1$

Step2: Subtract 7 from both sides

$17x + 7 - 7 = 1 - 7$
$17x = -6$

Step3: Divide both sides by 17

$\frac{17x}{17} = \frac{-6}{17}$

Answer:

$x = -\frac{6}{17}$
