✔ 最佳答案
1. 1/2k-150%=0.25k+1.50.5k-1.5=0.25k+1.5
0.25k=3
k=12
2. 2/9M+3-1=M/6
2/9M+2=M/6
4/18M+2=3/18M
M/18=-2
M=-36
3. R/5=R/6-7
6/30R=5/30R-7
R/30=-7
R=-210
4. M/5+2=3/10M-9
2/10M+2=3/10M-9
M/10=11
M=110
5. Y/3-2=3/8Y-4
8/24Y-2=9/24Y-4
Y/24=2
Y=48

1: ( 1/2= 0.5 150%=1.5 )0.5K-1.5=0.25+1.5
0.5K-1.5+1.5=0.25+1.5+1.5
0.5k=0.25+3
0.5k/0.5=3.25/0.5
K=6.5
2: (9 分之2M+3 再减一 =2/9m+3-1) 2/9m+3-1 =m/6
2/9m+2=m/6
m/6=2/9m+2
m/6-2 =2/9m
m x (1/6)-2=m x (2/9)
m x (3/18 )-2=m x (4/18)
2=m x (1/18)
2x18=m x (1/18) x18
36=m
m=36

2: (9 分之2M+3 再减一 =2/9m+3-1) 2/9m+3-1 =m/6
2/9m+2=m/6
