Answer:
(-9/2t + 3) +( 7/4t + 33) = -11/4t + 36
5(2t + 1)+(-7t +28) = 3t+ 33
Explanation
Those are the ones i could solve hope this helps!
1. Problem
(-9/2t + 3) +( 7/4t + 33)
-9/2t + 7/4t
-18/4t +7/4t= -11/4t
3+ 33= 36
-11/4t + 36
2. Problem
5(2t + 1)+(-7t +28)
10t + 5 + ( -7t +28)
10t - 7t= 3t
5+ 38= 33
