This is wrong because if you check your work, then both equations get different answers. So like 2(1.5) - 7 is negative 4. 11 - 4x is the same as 11 - 6 which is 5. But good try 👍🏽

-7 = 11 - 6x
-11 -11

-18 = -6x

I think it's 2 because:
2x-7=11-4x
-2x 2x
_________
7= 11-2x
11-7=4
2 x 2 =4
x=4

How to solve 2x-7=11-4x:
2x-7=11-4x
I used KCC because I wanted to get a better visual.

2x - 7 = 11 + -4x
- -2x - -2x
-------------------------------
-7 = 11 + -6x
- -11 -11
--------------------------------
-18 = -6x
÷ -6 ÷ -6
-------------------------------
3 = x

2(3)-7=11-4(3)
6-7=11-12
-1=-1

x=3 because..,
2x - 7 = 11 + -4x
- -2x - -2x
-------------------------------
-7 = 11 + -6x
- -11 - -11
--------------------------------
-18 = -6x
÷ -6 ÷ -6
which equals to 3=x (or x=3)

2x - 7 = 11 - 4x
k c c k c c
2x + -7 = 11 + -4x
- 2x - 2x
*********************
-7 = 11 + -6x
-11 -11
*********************
-18 = -6x
/ -6 = /-6
*********************
3 = x

Check:

2 * 3 - 7
6-7
-1

11 - 4 * 3
11 - 12
- 1

-1 = -1 : )

The answer is x = 3

The first step was tricky because of the negative. Deven solved it first with this step:

2x - 7 = 11 - 4x
-2x -2x
———————--
-7 = 11 - 6x


Hannah was the first to use KCC to see it better:
2x - 7 = 11 - 4x
k c c k c c
2x + -7 = 11 + -4x
- 2x - 2x
*********************
-7 = 11 + -6x



And Michael decided to go the other way and inverse the -4x first:
2x - 7 = 11 - 4x
+4x +4x
6x - 7 = 11
