    7y+44=12y+11 => 5y = 33 => y=33/5

    (7t-21)+(t+4)=15 => 6t = 32 => t=16/3

    8x-4-2x = -10 =>6x=-6 => x=-1

    (8t+30)+(-2t-16)= -22 => 6t=-36 => t=-6

    7y+44=12y+11

    7y - 12y = 11 - 44

    -5y = -33

    y = 33/5

    (7t-21)+(t+4)=15

    7t - 21 + t + 4 = 15

    8t -17 = 15

    8t = 15 +17

    8t = 32

    t =32/8

    t = 4

    Solve: 8x-4-2x+ -10 = ???

    (8t+30)+(-2t-16)= -22

    8t + 30 - 2t - 16 = -22

    6t + 14 = -22

    6t = -36

    t = -36/6

    t = -6

    1] 12y-7y=44-11

    =5y=33

    =y=33/5

    2]7t-21+t+4=15

    =8t=32

    t=4

    3]6x=4-10

    6x=-6

    x= -1

    4]6t=-36

    t=-6
