Question

2.2x+2.3×2=5.04怎么检验

Answer 1

2.2x+2.3×2=5.04
2.2x+4.6 = 5.04
2.2x = 5.04 - 4.6
2.2x = 0.44
x=0.44 ÷2.2
x=0.2
将x=0.2带入方程，方程的左边 = 2.2x0.2+2.3x2 = 0.44+4.6 = 5.04
方程的右边 = 5.04
方程左边 = 方程右边，故x=0.2是方程2.2x+2.3×2=5.04的解

Answer 2

解方程过程如下
2.2x+2.3×2=5.04
2.2x+4.6=5.04
2.2x=5.04-4.6
2.2x=0.44
x=0.44÷2.2
x=0.2
验算：2.2×0.2+2.3×2=0.44+4.6=5.04
