x÷0.8+7.6=10解方程怎么写,急急急

x÷0.8=10-7.6 x÷0.8=2.4 x=1.92

(x+0.8)÷6=7.2 x+0.8=7.2x6 x+0.8=43.2 x=43.2-0.8 x=42.4

(x+0.8)÷6=7.2 解:(x+0.8)÷6×6=7.2×6 x+0.8=43.2 x+0.8-0.8=43.2-0.8 x=42.6

x÷7+4=7.8 x÷7=3.8 x=26.6 ~回答完毕~ ~结果仅供参考~ ~\(^o^)/~祝学习进步~~~

5.5x+6.7=7.8解:5.5x=1.1x=0.23.5x-0.8x=11.34解:2.7x=11.34x=4.228-x+3.6=20解:31.6-x=20x=11.68x-27.54/2.7=1.8解:8x-10.2=1.88x=12x=1.59x-14*5.5=58解:9x-77=589x=135x=15

X/0.7=0.7 x=0.49 2X-5.7=9.6 x= 7.65 (X-0.7)*0.8=2.8 x=2.24 0.56*3.68+6.32*0.56=0.56*(3.68+6.32)=0.56*10=5.6 7.8*10.1=7.8*(10+0.1)=78+0.78=78.78 1-十四分之八=七分之三 2.6/0.31=260/31=8又31分之12 83.2/9.3=8又93分之88 8.23/1.6=0.5...

0.4x+(8+x)×0.8=13.6 0.4x+6.4+0.8x=13.6 0.4x+0.8x=13.6-6.4 1.2x=7.2 x=7.2÷1.2 x=6 亲,请【采纳答案】,您的采纳是我答题的动力,谢谢。

(1)50%x+30%x=8, 0.8x=8, 0.8x÷0.8=8÷0.8, x=10;(2)x-40%x=90, 0.6x=90, 0.6x÷0.6=90÷0.6, x=150;(3)4x+3×0.7=6.5, 4x+2.1=6.5, 4x+2.1-2.1=6.5-2.1, 4x=4.4, 4x÷4=4.4÷4, x=1.1;(4)8x+42=178, 8x+42-42=178-42, 8x=136...

(1)10x-6.5=73.5, 10x-6.5+6.5=73.5+6.5, 10x÷10=80÷10,x=8;(2)23x÷1.2=115,23x÷1.2×1.2=115×1.2, 23x÷23=138÷23, x=6;(3)2.4÷(x-15)=12,2.4÷(x-15)×(x+15)=12×(x-15), 12×(x-15)=24,12×(x-15)÷12=24÷12, x-15=2...

(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)...
