✔ 最佳答案
1.1+a = 10
a = 10-1
a = 9

2.11-a = 22.5
-a = 22.5-11
-a = 11.5

3.11+a = 22.5
a = 22.5-11
a = 11.5

1. 1+a=10
1+a-1=10-1
a=9

2. i don't no


3. 11+a=22.5
11+a-11=22.5-11
a=11.5

1+a=10
a=10-1
a=9


11-a=22.5
-a=22.5-11
-a=11.5
a=-11.5


11+a=22.5
a=22.5-11
a=11.5

1.
1+a=10
a=10-1
a=9

2.
11-a=22.5
-a=22.5-11 <.....-a姐係-1 x a
-1a=11.5
a=11.5x-1
a=-11.5

3.
11+a=22.5
a=22.5-11
a=11.5

1.1+a=10
a=10-1
a=9
2. 11-a=22.5
11-22.5=a
a=-11.5
3.11+a=22.5
a=22.5-11
a=11.4
