    1-15 = 2t - 11

    -14 = 2t-11

    move - 11 to the other side

    sign changes from - 11 to + 11

    -14+11 = 2t-11+11

    -14+11 = 2t

    -3 = 2t

    divide both sides by 2 to get t by itself

    -3/2 = 2t/2

    Answer:

    t = - 3/2, t = - 1.5 and t = - 1 1/2

    Answer: t=-3/2

    step-by-step:

    okay so in order to do this problem, it's best if you combine the 1 and - 15 into - 14

    -14=2t-11

    next, you wanna add 11 to both sides to get rid of the eleven on the right

    -14+11=2t-11+11

    and that makes

    -3=2t

    (-14+11=-3 and 2t-11+11=2t)

    now you want to divide each side by 2

    -3/2=2t/2

    2t/2=t so that makes your final answer t=-3/2
