Can someone please help with these equations?!?
1.8k=6k-26
2.5/8a+6=3/4a
3.1/4n+10=2/3n
4. 20-1/5d=3/10d+16

  • Math - ,

    1.
    8k=6k-26
    2k = -26
    k = -13

    2.
    5/8a +6 = 6/8a
    6 = 1/8a
    48 = a

    3.
    3/12n +10 = 8/12n
    10 = 5/12n
    120 = 5n
    24 = n

    4.
    20 - 2/10d = 3/10d +16
    4 = 1/2d
    8 = d

    (I think. You should check.)
