Answer 9

Check the signs that happened during the transition

Answer 10

this is really confusing

Answer 11

In the first line you have your equation and throughout the whole process they are just solving for x

Answer 12

so it's line 3

Answer 13

You can see that the first thing they did is subtract 4x from both sides so if you do it out what should be left?

Answer 14

Correct it is line 3 but do you know why?

Answer 15

i just realized that they were subtracting and stuff and then the whole process changes in line 3 because they're now solving for x

Answer 16

Nope

Answer 17

The mistake is not that they are solving for X but that in the transition a number was changed from negative to positive that should not have been to be consistent with the algebra
