✔ 最佳答案
16.5=24-3t3t=7.5
t=2.5
6-10/15w=30-4/3w
-24=10/15w
w=-24*15/10=-36
x-47/9=3x/7-5/3
4x/7=32/9
x=32/9*7/4=56/9=6 2/9
5c/2+6=8c/3
15c+36=16c
c=36

16又2分1=24--3t=
3t = 24-16.5
3t = 7.5
t = 2.5
6-15分10w=30--1又3分1w
-10w/15 + 4w/3 = 30-6
10w/15 = 24
10w = 360
w = 36
x-5又9分2=7分之3x-1又3分2
x - 47/9 = 3x/7 - 5/3
x - 3x/7 = -5/3 + 47/9
4x/7 = 32/9
4x = 224/9
x = 56/9
2分之5c+6=3分之8c
5c/2 +6 = 8c/3
15c + 36 = 16c
36 = c
3t = 24-16.5
3t = 7.5
t = 2.5
6-15分10w=30--1又3分1w
-10w/15 + 4w/3 = 30-6
10w/15 = 24
10w = 360
w = 36
x-5又9分2=7分之3x-1又3分2
x - 47/9 = 3x/7 - 5/3
x - 3x/7 = -5/3 + 47/9
4x/7 = 32/9
4x = 224/9
x = 56/9
2分之5c+6=3分之8c
5c/2 +6 = 8c/3
15c + 36 = 16c
36 = c
