Question

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

3 + 4x, because (12x − 8x) + 3 = 4x + 3 = 3 + 4x
7x, because 12x − 8x + 3 = 4x + 3 = 7x
12x − 5, because 12x − (8x − 3) = 12x − 5
x, because 12x − 8x + 3 = 12x − 11x = x

Answer 1

it is 3+4x because (12x+3)+3=4X+3=3+4x

Answer 2

A. 3 + 4x, because (12x − 8x) + 3 = 4x + 3 = 3 + 4x.

Explanation:
