2 answers:
U multiply the 8 into the brackets, same with the 5 to get 16+8t - 5t -5, now you can isolate the t, 11+3t, divide it all by 3, to get 11/3+t, now move the 11/3 to the other side of the = to get, -11/3=t
Answer:
21 + 3t
Step-by-step explanation:
Use distributive property: a*(b +c) =(a*b) + (a*c)
8(2 +t) - 5(t - 1) = 2*8 + t *8 + t *(-5) - 1*(-5)
= 16 + 8t -5t + 5
= 16 + 5 + 8t - 5t {Combine like terms}
= 21 + 3t
