Question

Am I doing this right?
Which of these is a simplified form of the equation 7x + 4 = 5 + 3x + 1x?
A. 3x = 9
B. 3x = 1
C. 11x = 9
D. 11x = 1
My process:
7x + 4 = 5 + 3x + 1x
7x + 4 = 5 + 4x
7x + 4x = 5 + 4
11x + 9
So, I want to say C. Am I right?

Answer 1

let's look at your 7x+4=5+4x
you are right here
but there are incorrect steps take afterwards

Answer 2

What did I do wrong?

Answer 3

you know that 4x-4x=0
and that 4-4=0 right?

Answer 4

you are on the right track. Except when you put terms on another side, you must do the opposite

Answer 5

You have used that 4x+4x=0 and that 4+4=0 when this is not true

Answer 6

7x+4=5+4x

Pretend we want to get the x's on all one side right now
what do you think we must do to do this

Answer 7

I used the distribution property to move the 4 in the 4x's place.
