5x + 12 - 4x - 6 -2x - 5 + 2x = 1 + 1x
x + 1 = 1 + x
Yes it is correct

Start by getting rid of the parentheses (distributive property):
5x+12-4x-6-2x-5+2x=1+1x
Combine like terms (add constants with other constants and multiples of the variable together):
(5x-4x-2x+2x)+(12-6-5)=1+1x
1x+1=1+1x
If you then solve this for x, you will find that the x terms disappear:
0=0
This means that you could plug in any real value for x and have the equation be true.

5x + 12 - 4x - 6 - 2x - 5 + 2x = 1 + 1x
5x - 4x - 2x + 2x - x = 1 -12 +6 +5
0 = 0
the value of x can not be found

Let's simplify
5x +12 - 4x-6-2x-5+2x=1+1x
Combine like terms:
x+1=1+x
x=x
In any given problem, when x=x, there are an infinate number of solutions. The answer = "All Real Numbers"

p.e.m.d.a.s
parentheses, exponent, multiplication, division, addition, subtraction
so break it down
5x+12-4x-6-2x-5-2x
which is 1+1x

5x+4(3-x)-6-2x-(5-2x)
5x+12-4x-6-2x-5+2x
=x+1

x=3
Simplify:
5x+12-4x-6-2x-5+2x=1+1x
9x-23=1+1x
8x=24
x=3
