-8(t - 5) - (t + 4) = 3
-8(t - 5) - 1(t + 4) = 3
-8 * t = -8t
-8 * -5 = 40
-1 * t = -1t
-1 * 4 = -4

-8t + 40 - 1t - 4 = 3
Combine like terms:
-8t - 1t = -9t
40 - 4 = 36

-9t + 36 = 3
Subtract 36 from each side of the equation.
-9t + 36 - 36 = 3 - 36
Combine like terms:
36 - 36 = 0
3 - 36 = -33

-9t = -33
Divide each side by -9
-9t/-9 = -33/-9

The Answer:

t = 3.66667
