Answer 1

@iGreen

Answer 2

7x + 4 = 5 + 3x + 1x

First, combine 3x + 1x

Answer 3

3x + 1x is the same as 3 + 1 but we add an 'x' at the end.

Answer 4

4x?

Answer 5

Yep!

So we have:

7x + 4 = 5 + 4x

Now subtract 4x to both sides, what's 7x - 4x?

Answer 6

3x?

Answer 7

oh so its 3x=9?

Answer 8

Yep, that gives us:

3x + 4 = 5

Now subtract 4 to both sides

Answer 9

So its B!

Answer 10

????

Answer 11

Um, no..

Subtract 4 to both sides, what's 5 - 4?

Answer 12

1! OH I GET IT

Answer 13

ITS D!

Answer 14

Yep!

Answer 15

3x = 1
