Can you please help me with this? I don't really understand it.

Q: 5(x+10)+x

A. 6x + 15
B. 5x + 15
C. 6x + 50
D. 4x - 50

I tried to work out the problem and I came out with A. Am I right? Thanks.

    No.

    5(x+10)+x

    5x + 50 + x = 6x + 50

    Oh I see it now. I get why I got it wrong.

    Could you also help me with another math problem? Every time I do the problem my answer isn't coming out right.

  • Math - ,

    Sure. Please post the problem.

  • Math - ,

    Okay thank you.

    -4n + 7 + 2n = 1

    A. 1
    B. 3
    C. -3
    D. 4

  • Math - ,

    -4n + 7 + 2n = 1

    -2n + 7 = 1

    -2n - -6

    n = 3

    Oh okay, I was doing it completely wrong. Thank you so much Ms. Sue.

    You're very welcome.
