6x - 12 + 2x = 3 + 8x - 15
--------------------------
This equation is always true.
It is an identity.
To get the conclusion, simplify this equation as you usually do.
It means: collect the terms with x; collect the constant terms etc.
In this way you will get
(6x + 2x - 8x) + (-12 -3 + 15) = 0, or
0*x + 0 = 0, or
0 = 0.
This equation is always true, so the original equation is.
