5X=48-3X
5X-3X+3X=48-3X+3X
5X+3X=48
8X(devide 8)=48(devide 8)
X=6
驗算:
6乘5=48-3乘6
30=48-18
30=30
(6=X)
5X-3X+3X=48-3X+3X
5X+3X=48
8X(devide 8)=48(devide 8)
X=6
驗算:
6乘5=48-3乘6
30=48-18
30=30
(6=X)

5x= 48-3x
5x+3x=48
8x=48
8x除以8(要用分數表示)=8份之48(要用分數表示)
x=6
5x+3x=48
8x=48
8x除以8(要用分數表示)=8份之48(要用分數表示)
x=6

5x = 48 - 3x
5x + 3x = 48
8x = 48
x = 6
5x + 3x = 48
8x = 48
x = 6
