Question

x+1.2×5+3+x=24.4解方程并检验？

Answer 1

2x+6+3=24.4
2x=24.4-9
2x=15.4
x=7.7
检乎樱饥验：将x=7.7代颂闷入原岁返式：
7.7+1.2x5+3+7.7
=7.7+6+3+7.7
=13.7+3+7.7
=16.7+7.7
=24.4

Answer 2

x+1.2×5+3+x=24.4解方衡袜程并检验？此和
解咐扒激：x+1.2*5+3+x=24.4
2x=24.4-3-6=15.4
x=7.7
检验：7.7+1.2*5+3+7.7=7.7+6+3+7.7=24.4

Answer 3

解：2x＋6＋3＝闭咐弊24.4
2x＋9＝轿族24.4
2x＝24.4－9
2x=15.4
x＝15.4÷2
x=7.7
检简橘验：7.7+1.2×5+3+7.7=24.4

Answer 4

2x+6+3=24.4,
2x=15.4,
x=7.7,
检验：x=7.7时左边=7.7+1.2×5+3+7.7
=7.7+6+10.7
=24.4=右边，
所以x=7.7是方耐数伍毕中程昌或的解。

Answer 5

解:
2x+9=24.4
2x=15.4
x=7.7
检验:
7.7+6+3+7.7=24.4
