解: x+5.6-5.6 =9.52-5.6 x =3.92
解: x÷2.4×2.4 =1.8×2.4 x =4.32
解:2.4x=0.96 x=0.96÷2.4 x=0.4
解:7x-1.4+1.4 =4.9+1.4 7x =6.3 7x÷7 =6.3÷7 x =0.9
解:9.6+3x-9.6 =30-9.6 3x =20.4 3x÷3 =20.4÷3 x =6.8
解: 0.5x+7.2 =14.5 0.5x+7.2-7.2 =14.5-7.2 0.5x =7.3 0.5x÷0.5 =7.3÷0.5 x =14.6
y+28.5=79.6 解:y=79.6-28.5 x=51.1
2x+15×3=62.6 解:2x+45=62.6 2x=17.6 x=8.8
解:设神舟十六号航天员在太空中度过一昼夜 是x小时。 16x=24 x=24÷16 x=1.5 答:神舟十六号航天员在太空中度过一昼夜是 1.5小时。
