not so sure about this one either.
(anything typed such as 7/6 are fractions, not sure how to type it.

x+7/6=2x-7/6

6(x+7/6)=6(2x-7/6)
6x+7=12x-7
-6x -6x
7=6x-7
+7 +7
6x/6= -14/6

  • math 012 - ,

    x = 14/6 = 7/3 is the correct answer.

    Your error was made in the last step. You should have come up with 6x = 14

    do you mind to show me how you got that answer. i am lost after the 2nd step. thanks

  • math 012 - ,

    x+7/6=2x-7/6

    6(x+7/6)=6(2x-7/6)
    6x+7=12x-7

    Subtract 6x from both sides and add 7 to both sides.

    6x = 14
    x = 14/6 = 7/3 = 2 1/3

    I hope this helps a little more. Thanks for asking.
