    t = 11.

    Step-by-step explanation:

    7 - 1 (5t - 13) = - 25.

    Distribute the - 1.

    7 - 5t + 13 = - 25

    Combine like terms.

    20 - 5t = - 25

    Subtract 20 from both sides.

    -5t = - 55

    Divide by - 5.

    t = 11.

    t = 9

    7 - 1 (5t - 13) = - 25

    7 - 5t + 13 = - 25

    -5t + 20 = - 25

    -20 - 20

    -5t = - 45

    divide - 5 from both sides of the equal sign

    t = 9
