x%1.7=2.5的解方程怎么写

x-1.7=2.5的解方程 解:x=2.5+1.7 x=4.2

x一1.2=6.7 解:原方程即: x一1.2=6.7 x=1.2+6.7 x=7.9

x=1.7+2.5 x=4.2 很高兴为你解答有用请采纳

x=0.5 x=0.5 x=0.5望采纳

x÷1.7等于0.6 x等于0.6×1.7 x等于1.08

(1)2(x+1.7)=9.2, 2(x+1.7)=9.2÷2, x+1.7=4.6,x+1.7-1.7=4.6-1.7x=2.9;(2)8x-4x=0.64, 4x=0.64,, 4x÷4=0.64÷4,x=0.16; (3)2x-0.24=0.12,2x-0.24+0.24=0.24+0.12, 2x=0.36, 2x÷2=0.36÷2x=0.18;(4)6.2x-x=416, 5.2x=41...

解如图。

(1+1.7)x=8.1 2.7x=8.1 x=3;

(1)x+6.6=8.4 x+6.6-6.6=8.4-6.6 x=1.8;(2)0.93÷x=0.31 0.93÷x×x=0.31x 0.93=0.31x 0.31x=0.93 0.31x÷0.31=0.93÷0.31 x=3; (3)x-1.2=6.7 x-1.2+1.2=6.7+1.2 x=7.9验算:左边=7.9-1.2=6.7右边=0.7左边=右边,所以7.9是原方程的解; (4)...

x-1.7x3=4.9 x-5.1=4.9 x=4.9+5.1 x=10
