Answer:
11x - 12
Explanation:
First, group like terms (numbers with a coefficient (x) together)
12x - 3x + 2x -10 -2
Next, use BODMAS (brackets, of, division, multiplication, addition, subtraction) to know the order to solve.
Addition is before subtraction so we do: -3x + 2x which is -x
12x - x - 10 -2
12x - x = 11x and -10 -2 ÷ -12 so final answer is:
11x -12
