1. 6/z - 4.4 = 0.4
6/z = 4.8
6 = 4.8z
6/4.8 = z
1.25 = z
z = 1.25
6/z = 4.8
6 = 4.8z
6/4.8 = z
1.25 = z
z = 1.25

6÷z-4.4=0.4
6÷z=0.4+4.4
6÷z=4.8
6=4.8z
6÷4.8=z
1.25=z
z=1.25
6÷z=0.4+4.4
6÷z=4.8
6=4.8z
6÷4.8=z
1.25=z
z=1.25

6÷z-4.4=0.4
6÷z-4.4+4.4=0.4+4.4
6÷z×6=4.8×6
z=28.8
6÷z-4.4+4.4=0.4+4.4
6÷z×6=4.8×6
z=28.8

6 / (z - 4.4) = 0.4
6 = 0.4(z - 4.4)
6 = 0.4z - 1.76
0 = 0.4z - 1.76 - 6
0 = 0.4z - (-4.24)
0 = 0.4z + 4.24 (負負得正)
0.4z + 4.24 = 0
0.4z = -4.24
z = (-4.24) / 0.4
z = -10.6

我想問...
你話6除代數減4.4=0.4
甘有無括號嫁?!
係:
a) (6 / z) - 4.4 = 0.4
定係:
b) 6 / (z-4.4) = 0.4
6 = 0.4(z - 4.4)
6 = 0.4z - 1.76
0 = 0.4z - 1.76 - 6
0 = 0.4z - (-4.24)
0 = 0.4z + 4.24 (負負得正)
0.4z + 4.24 = 0
0.4z = -4.24
z = (-4.24) / 0.4
z = -10.6
