12 7/23 -(6 18/23 -t)= 3 21/23+5 19/23

Question

12 7/23 -(6 18/23 -t)= 3 21/23+5 19/23

Answer 1

12 7/23-6 18/23+t=3 21/23+5 19/23
t=3 21/23+5 19/23+6 18/23-12 7/23
t=4 5/23
12 7/23-(6 18/23-4 5/23)=3 21/23+5 19/23
9 17/23=9 17/23

Answer 2

12 7/23 - (6 18/23 - t) = 3 21/23 + 5 19/23
283/23 - (156/23 - t) = 90/23 + 134/23 = 224/23
156/23 - t = 283/23 - 224/23 = 59/23
t = 156/23 - 59/23 = 97/23 = 4 5/23
