Oh yes, I put a + sign instead of a = sign before the 3x and after the 7.

2(3x-4)-7 = 3x +1 +x
distribute 2
6x-8-7 = 3x +1 +x
combine -8 and -7, then 3x and x
6x - 15 = 4x +1
add 15 to both sides
6x= 4x + 16
subtract 4x from both sides
2x = 16
divide each side by 2
x=8

You would distritbute the 2 by multiplying it to the 3x and the 4. This way you get
6x - 8 - 7 +3x + 1 +x
Then you combine the like numbers=
10x-14

Well, first multiply the 2 by (3x - 4), which = 6x - 8
So, now you have 6x - 8 - 7 + 3x + 1 + x.
Now add all of the x values and integers together:
6x + 3x + x - 8 - 7 + 1
6x + 3x + x = 10x and
- 8 - 7 + 1 = -14
So, it becomes 10x -14. Since there is no = sign present, it is impossible to solve the value of x.

Step One: Distribute into the parentheses. This means you need to multiply 3x - 4 by 2.
2 (3x - 4) - 7 + 3x + 1 + x
6x - 8 - 7 + 3x + 1 + x
Step Two: Add all the x's together.
10x - 8 - 7 + 1
Step Three: Combine -8, -7 and 1.
10x - 14
Done!

you cannot solve for that. It is not an equation, it is a statement. If it is supposed to =0 then you can solve for it.
distribute parenthesis
(6x-8)-7+3x+1+x=0
add like terms
10x-14=0
10x=14
x=14/10
x=7/5

2(3x-4)-7=3x+1+x
distribute the 2
6x-8-7=3x+1+x
combine like terms (3x+x) and (-8-7)
6x-15=4x+1
subtract 4x from both sides
2x-15=1
add 15 to both sides
2x=16
divide both sides by 2
x=8

Are you supposed to simplify it or what? you cannot solve for X the way it is written.

you can't solve it, there is no equal sign. if you want to simplify it, that's possible.
