Which expression is equivalent to 12x − 8x + 3 and why?

A. 3 + 4x, because (12x − 8x) + 3 = 4x + 3 = 3 + 4x
B. 7x, because 12x − 8x + 3 = 4x + 3 = 7x
C. 12x − 5, because 12x − (8x − 3) = 12x − 5
D. x, because 12x − 8x + 3 = 12x − 11x = x

B,C and D are obviously WRONG

we cannot simply added expression in terms of x with number.That is wrong in math theory.We can only substract and add with the same expression.A is define the right solution
