x÷0.8+7.6=10解方程怎么写,急急急

X=(10-7.6)*0.8,结果是,X=1.92

(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加0.8)除于6等于7.6 (x+0.8)/6=7.6 解:x+0.8=7.6*6 解得:x=44.8

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...

(1)x-15%x=1.7+6.8, 0.85x=8.5, 0.85x÷0.85=8.5÷0.85, x=10;(2)34-8x=16,34-8x+8x-16=16+8x-16, 712=8x, 8x=712, 8x÷8=712÷8, x=796;(3)3×(x-3)=x-5, 3x-9=x-5, 3x-9-x+9=x-5-x+9, 2x=4, 2x÷2=4÷2, x=2;(4)72÷x=185...

0.7x=8.4 x=12

(x十0.8)/6=7.2 (x十0.8)=7.2x6 (x十0.8)=63.2 x=63.2+0.8 x=64

(1)8(x-2)=2(x+7), 8x-16=2x+14, 8x-16-2x=2x+14-2x, 6x-16+16=14+16, 6x÷6=30÷6, x=5;(2)x2=0.150.6, 0.6x=0.15×2,0.6x÷0.6=0.3÷0.6, x=0.5.

8-0.6x=1.7 0.6x=8-1.7 0.6x=6.3 x=10.5

0.6+0.7x=8.3 0.7x=7.7 x=1.1 3.6x-x=7.8 2.6x=7.8 x=3 2x-3.6=14.4 2x=10.8 x=5.4
