7th grade math, shouldn't be this hard.

Temka [501]

Answer:

x = 12

Step-by-step explanation:

Step 1: Add 9 to both sides.

$7x - 9 + 9 = 75 + 9$
$7x = 84$

Step 2: Divide both sides by 7.

$\frac{7x}{7} = \frac{84}{7}$
$x = 12$

Step 3: Check if solution is correct.

$7(12) - 9 = 75$
$84 - 9 = 75$
$75 = 75$

Therefore, x = 12.
