please help thank you

Answer:
(-9/2t + 3) + (7/4t + 33) = -11/4t + 36
3(3t - 4) - (2t + 10) = 7t + 22
5(2t + 1) + (-7t + 28) = 3t + 33
(4t + 8/5) - (3 - 4/3t) = 16/3t - 23/5
Step-by-step explanation:
Pair 1:
(-9/2t + 3) + (7/4t + 33)
-11/4t + 3 + 33
-11/4t + 36 is equivalent
Pair 2:
3(3t - 4) - (2t + 10)
9t - 12 - (2t + 10)
9t - 12 - 2t - 10
7t - 12 - 10
7t - 22 is equivalent
Pair 3:
5(2t + 1) + (-7t + 28)
10t + 5 + (-7t + 28)
10t + 5 - 7t + 28
3t + 5 + 28
3t + 33 is equivalent
Pair 4:
(4t + 8/5) - (3 - 4/3t)
4t - 8/5 - 3 - (-4/3t)
4t - 8/5 - 3 + 4/3t
4t - 8/5 - 15/5 + 4/3t
4t - 23/5 + 4/3t
12/3t - 23/5 + 4/3t
16/3t - 23/5 is equivalent
