    Hello there. So for this, you need to use the distributive property. do you remember what that is?

    Great so do the distributive property on 5(x-2) Ignore the +3x, we can add that in later.

    Almost. Remember that a*(b*c) = (a*b) + (a*c) So for this question you did the first part...

    You also need to distribute the 5 to the 2.

    5(x-2) So 5 is the a x is the b and -2 is the c (5*x) + (5 * -2)

    What you should get is (5x) + (-10)

    That's basically 5x - 10. Are you following so far?

    Cool so now all we have left is the +3x which was not part of the distribution. So 5x + 3x = 8x. Our answer will be 8x - 10. Don't forget to distribute the second part.
