✔ 最佳答案
22-5m=7
-5m=7-22 (因為戈個22本身系正22,,將佢調轉就系-22,,,數字前面個負號系跟住後面個數so系-5m)
-5m=-15
m=3^^

22-5m=7
左右兩邊同時減22 22-5m-22=7-22
兩個22互相詆消 因5m要跟左面的減 -5m= -15
m= -15/-5
m=3

22 - 5m = 7,

So that 22 - 7 = 5m

Therefore 15 = 5m hence m = 15/5 = 3

Good luck!

22-5m=7
22-5m+5m=7+5m
22=7+5m
22-7=5m
15=5m
5m=15
5m除以5=15除以5
m=3

22-5m=7
-5m=7-22
-5m=-15
-m=-3
m=3

22-5m=7 (a-b=c...a-c=b)
22-7=5m
15=5m
3=m
m=3

答案係3.
