    Do you need me to explain it, or to just give you an answer?

    I do not want an answer, I just want someone to kind-of watch my work, so that I know I am solving it the right way. Asking for the answer would be against openstudy policies...

    first, I would solve the multiplication, so 5x-2=-10, and 3x2=6, so -10-6-(-3), right?

    okay.. next, it would become -16- (-3), right, since we subtract 6 from -10?

    not really, both are negative, and we are not multiplying?

    6 - (-3) When there are 2 minus signs, you add 6 + 3

    -16 - (-3) = -16 + 3 = -13
