Question

solve the equation $9x - 7 = -7$ and choose the correct answer from the options: 1, 0, $\frac{-9}{14}$, $\frac{7}{9}$

Explanation:

Step1: Isolate the term with $x$

Add 7 to both sides of the equation:
$$9x - 7 + 7 = -7 + 7$$
$$9x = 0$$

Step2: Solve for $x$

Divide both sides by 9:
$$x = \frac{0}{9}$$
$$x = 0$$

Answer:

0
