解方程:(2x-1)/0.2=7-(x+0.3)/0.5
问题描述:
解方程:(2x-1)/0.2=7-(x+0.3)/0.5
答
(2x-1)/0.2=7-(x+0.3)/0.5
5(2x-1)=7-2(x+0.3)
10x-5=7-2x-0.6
10x+2x=7+5-0.6
12x=11.4
x=11.4÷12
x=0.95
答
(2x-1)/0.2=7-(x+0.3)/0.5 两边同时乘以1得
5(2x-1)=7-2(x+0.3)
10x-5=7-2x-0.6
10x+2x=7-0.6+5
12x=11.4
x=11.4÷12
x=0.95
答
(2x-1)/0.2=7-(x+0.3)/0.5
10X-5=7-2X-0.6
12X=11.4
X=0.95
答
5(2x-1)=7-2(x+0.3)
10x-5=7-2x-0.6
12x=11.4
∴x=0.95
答
(2x-1)/0.2=7-(x+0.3)/0.5
10x-5=7-2(x+0.3)
10x-5=7-2x-0.6
10x+2x=7+5-0.6
12x=11.4
x=11.4÷12
x=19/20
