Question

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

Answer 1

x = 12

Explanation:

This is a multi-step equation.

The first thing we can do is add 9 to both sides, eliminating the -9 from the left side of the equation. Now we have 7x = 84.

You can divide 84 over 7x to get a total of x =12.

Answer 2

x = 12

Explanation:

Step 1: Add 9 to both sides.

• 
  `7x - 9 + 9 = 75 + 9`
• 
  `7x = 84`

Step 2: Divide both sides by 7.

• 
  `(7x)/(7) = (84)/(7)`
• 
  `x = 12`

Step 3: Check if solution is correct.

• 
  `7(12) - 9 = 75`
• 
  `84 - 9 = 75`
• 
  `75 = 75`

Therefore, x = 12.
