    t = (y + 10) / 2

    Step-by-step explanation:

    Make t the subject in

    2 (t - 5) = y

    Step 1

    Expand the bracket by multiplying each term in the bracket by 2

    2Xt - 2X5 = 2t - 10

    2t - 10 = y

    Step 2

    To move 10 to the other side of the right hand side (RHS) of the equation, we add 10 to both sides of the equation.

    2t - 10 + 10 = y + 10

    2t = y + 10

    Step 3

    Make t the subject by dividing both sides of the equation by its coefficient, 2

    2t/2 = (y + 10) / 2

    t = y+10 / 2
