If the problem is: 3x-22 = x+80 what would x equal? Please show your work.

  1. Samantha

    Wouldn't x equal 51?

  2. MathGuru

    Let's see if your answer checks by substituting 51 for x:

    3(51) - 22 = 51 + 80
    153 - 22 = 131
    131 = 131

    It checks, so you are correct!

  3. Steve

    you are correct.

    Which you could have determined by evaluating

    3*51 - 22 =?= 51+80
    153-22 =?= 131
    yes

  4. Ms. Sue

    Yes.
