解方程。X除以18等于24

1,(x+18)÷(x÷13.5)=x÷ (X+18)((X+18)/24=X*X/13.5 13.5(x+18)^2-x^2*24=0 9(x+18)^2-16x^2=0 (3x+54+4x)(3x+54-4x)=0 (7x+54)(-x+54)=0 x1=54,x2=-54/7 2,12÷x*12-1=12÷(x+2) *12 144/x-1=144/(x+2) (144-x)(x+2)=144x -x^2+142x+288=144x x^2+2x-288=0 (x-16)(x+18)=0(根据十字相乘法)所以,x=16或x=-18

x/18=3.6 解: x=64.8 2x+3.4=9.6 2x=6.2 x=3.1 3x-6*12=24 3x-72=24 3x=96 x=32 6.8x-0.8x=0.48 6x=0.48 x=0.08 5(16-x)=35解:80-5x=35 45=5x x=9

解题步骤如下:x÷18=24 解:去分母,得 (x÷18)*18=24*18,即 x=24*18,解得 x=432.望采纳,希望能够帮助到你!

先通分,化为(4/72)x+(3/72)x=5,则(7/72)x=5,x=360/7

24÷*=18解:x=24÷18x=4÷3x=1.3333333333

∵x÷6=18,∴x=108. 4x=24, ∴x=6. 4x/5=12/13,∴4x13=5 12,∴x=15/13, 6x/7=(2/5)(3/14), ∴x=(2/5)(3/14)(7/6),∴x=2/5 x÷8/21=13/15 ÷26/35, ∴21x/8=(13/15)(35/26) ∴x=(7/6) (8/21) ∴x=4/9

(1)24-x=18, 24-x+x=18+x, 18+x=24, 18+x-18=24-18, x=6;(2)x÷3 4 =1 3 , x÷3 4 *3 4 =1 3 *3 4 , x=1 4 ;(3)3 5 x-2 5 x=15, (3 5 -2 5 )x=15,1 5 x=15,1 5 x*5=15*5, x=75.

(1)18÷X= 6 7 , 18÷X*X= 6 7 *X, 18* 7 6 = 6 7 *X* 7 6 , X=21;(2)X- 3 20 X=34, 17 20 X=34, 17 2

18:X=3:1 3x=18x=18/3x=610:X=8:58x=50x=50/8x=25/40.8X=0.12+4.80.8x=4.92x=4.92/0.8x=6.1575:X=5:4 5x=75*4x=75*4/5x=603X=12÷0.53x=24x=24/3x=8 1.5:X=100:5 100x=1.5*5x=7.5/100x=0.075

[(24+X)÷18]÷2=486(24+X)÷18=972 24+X=17496 X=17472
