9, 5, 3, 2The steps below show the incomplete solution to find the value of x for the equation
5x − 2x − 3 = −2 + 15:

Step 1: 5x − 2x − 3 = −2 + 15
Step 2: 5x − 2x − 3 = 13
Step 3: 3x − 3 = 13

Which of these is most likely the next step?
3x = 16, 3x = 10, 3x = 39, 3x = 3

Answer 1

18.5

Explanation:

i just took the test

Answer 2

1 - z = 37/2 (Or 18 1/2)
2 - One
3 - z = 0
4 - x = 2
5 - Here are the steps to solve:
Step 1: Simplify both sides of the equation.
Step 2: Add 3 to both sides.
Step 3: Divide both sides by 3.

Hope this helps! :>
