5x%1%2÷3=8怎么解方程

4/5x =2/3×1/2 4/5X=1/3 X=1/3×5/4 X=5/12 请采纳

5x-1/3=1/2 5x=1/2+1/3 5x=5/6 x=5/6*1/5 x=1/6 (1-5/8)x=10 x=10÷3/8 x=10*8/3 x=80/3 8-(3/4+2/3x)=0 8-3/4-2x/3=0 2x/3=29/4 x=29/4*3/2 x=87/8 1/5×8÷x=5/8 8/5x=5/8 25x=64 x=64/25

x=4;x=5/8

(2x-1)÷2-x+2=(5x+2)÷3-(x+3)÷6 两边同乘以6 3(2x-1)-6x+12=2(5x+2)-(x+3) 6x-3-6x+12=10x+4-x-3 9=9x+1 9x=9-1 9x=8 x=8/9

(4x+14)÷(x+2)=5 4x+14 =5x+10 14-10 =5x-4x x =4 (13x+8)÷3=5x-1 13x+8=15x-3 11=2x x=5.5 如有疑问 可以追问 不要客气

x-1/2=3/4 x=3/4+1/2 x=5/4 65-8x=25 8x=65-25 8x=40 x=5 3/5x÷1/3=12 9/5x=12 x=12÷9/5 x=20/3

(1)5x-2×0.8=33.4 5x-1.6+1.6=33.4+1.6 5x=35 5x÷5=35÷5 x=7;(2)3(x-2.4)=8.4 3(x-2.4)÷3=8.4÷3 x-2.4=2.8 x-2.4+2.4=2.8+2.4 x=5.2;(3)4.2x÷1.6=1.054.2x÷1.6×1.6=1.05×1.6 4.2x=1.68 4.2x÷4.2=1.68÷4.2 x=0.4;(4)1.2x+8.8x=0.2...

解: X÷5/6=30 X=30×5/6 X=25 3/5X-1/4X=7 (12-5)X=280 X=280÷7 X=40 8/11:10=4/5:X X=10×4/5÷8/11 X=11 X:28%=1又3/4:0.7 0.7X=0.49 X=0.7 1/2+1/3X=10 1/3X=9.5 X=9.5×3 X=28.5 486-23x16=486-368=118 97x97/98=(98-1)×97/98=97-97/98...
