Question

7.8x=27.3、x除以5.6=9.8、6x-x-37.6=26.9、（x-4）x3=9.6、

Answer 1

7.8x=27.3

x=27.3÷7.8

x=3.5

x除以5.6=9.8

x=9.8x5.6

x=54.88

6x-x-37.6=26.9

5x=26.9+37.6

x= 7.8x=27.3

x=27.3÷7.8

x=3.5

x除以5.6=9.8

x=9.8x5.6

x=54.88

6x-x-37.6=26.9

5x=26.9+37.6

x=12.9

（x-4）x3=9.6

3x-12=9.6

3x=21.6

x=7.2

12.9

（x-4）x3=9.6

3x-12=9.6

3x=21.6

x=7.2
