PLEASE HELP!!! 90 POINTS FOR 2 MULTIPLE CHOICE QUESTION!!!

The steps below show the incomplete solution to find the value of x for the equation
5x − 2x − 3 = −2 + 17:

Step 1: 5x − 2x − 3 = −2 + 17
Step 2: 5x − 2x − 3 = 15
Step 3: 3x − 3 = 15

Which of these is most likely the next step?

3x = 5
3x = 12
3x = 18
3x = 45

How many solutions can be found for the equation 3x − 2 = 3x + 5?

Zero
One
Two
Infinitely Many

Answer 1

3x=18

Explanation:

3x-3=15

+3 +3

3X=18

second one is: 3x-2=3x+5

+2 +2

3x=3x7

+3x +3x

6X=7

Answer 2

(1) Next likely step is

3x = 18 (adding +3 to both sides of the eq.)

(2) 3x -2 = 3x + 5

simplify:

3x-3x = 5+2

0 = 7

This is never true, no matter what value of x is. So there is no (or zero) solution.

The answer is "Zero"
