✔ 最佳答案
1.5h+1-4h=10 1.5h-4h=10-1
-2.5h=9
(-2.5h)÷(-2.5)=9÷(-2.5)
h=-3.6

4h-1.5h-1= -10
4h-1.5h= -9
2.5h= -9
h= -9/2.5
h=3.6

打小左個 - tim^^..答案係 -3.6
4h-1.5h= -9
2.5h= -9

-2.5h+1-1=10-1
-2.5h=9
-2.5h*(-1)=9*(-1)
2.5h=-9
2.5h/2.5=9/2.5
h=3.6
-2.5h=9
-2.5h*(-1)=9*(-1)
2.5h=-9
2.5h/2.5=9/2.5
h=3.6

1.5h + 1 - 4h = 10
(1.5 - 4)h = 9
-2.5 h = 9
h = -3.6
(1.5 - 4)h = 9
-2.5 h = 9
h = -3.6
