There's a question in my textbook:

$$5x-6-(3x-2)$$

I think I misunderstood as I put the following for my working out:

$$5x-6-3x-2$$

And from that I got:

$$2x-8$$

Can anyone help me to understand how to get the right answer?

    When you subtract (3x-2), you need to change the sign on both 3x and -2. So $5x - 6 - (3x - 2) = 5x - 6 - 3x + 2$.2011-09-22
