    Okay. Well, the first...let's rearrange it so it's easier to see. 26x - 16x + 8 - 6 Now, since 26 and 16 are both multiplied by x, you can add them together. And I assume you know how to add 8 and -6!

    you just have to remember to carry the signs with the coefficients. Coefficient just means the number multiplied by the variable - from the first question, 26 and -16 are the coefficients of x.

    8-6 = 2, yes, but you need to keep the 10x. So the final answer will be 10x - 2
