✔ 最佳答案
(2 - t/4) - t = 2t - 3/52 - t/4-t+t = 2t -3/5 + t
2 - t/4 = 3t -3/5
2+ 3/5 = 3t + t/4
13/5 = 3t + t/4
3/5 x 4 = 13t/4 x 4
10.4= 13t
10.4/13=13t/13
0.8=t
t=0.8

check:L.H.S=(2 - 0.8/4) - 0.8 =(2-0.2)-0.8 =1.8-0.8 =1R.H.S=2x0.8 - 3/5 =1.6-0.6 =11=1L.H.S=R.H.S.

(2 - t/4) - t = 2t - 3/5
2 - t/4 = 2t -3/5 + t
2 - t/4 = 3t -3/5
2+ 3/5 = 3t + t/4
13/5 = (12t + t)/4
13/5 x 4 = 13t
10.4/13 = t
t = 0.8
2 - t/4 = 2t -3/5 + t
2 - t/4 = 3t -3/5
2+ 3/5 = 3t + t/4
13/5 = (12t + t)/4
13/5 x 4 = 13t
10.4/13 = t
t = 0.8
