6.3x/4=2.52 解方程

6.3x=2.52×4 x=9.08÷6.3 x≈0.144

6.3(x+2)=4(x+4) 解:6.3x+12.6=4x+16 6.3x-4x=16-12.6 2.3x=3.4 x=34/23

(1) 5/2:x=5/4:60 (5/2)/x=(5/4)/60 (5/4)x=(5/2)60 x=120 (2) 6.3/0.2=x/5 x =(6.3/0.2)5 = 6.3 (3) 0.6:x=15:1 0.6/x = 15/1 x=0.6/15 =1/25 (4) 12:14=x:6/1 12/14=(x/6)/1 x = 36/7

5.6x + 6.3 = 28.7, 5.6x = 22.4, 28x = 112, x = 4,

(1)4.2x-2.7×4=6, 4.2x-10.8+10.8=6+10.8, 4.2x=16.8, 4.2x÷4.2=16.8÷4.2, x=4;(2)0.8x+x=5.4, 1.8x=5.4, 1.8x÷1.8=5.4÷1.8, x=3;(3)2x-3.4=7.2, 2x-3.4+3.4=7.2+3.4, 2x=10.6, 2x÷2=10.6÷2, x=5.3;(4)5.3+3x=6.8, 5.3+...

(1-40%)x=6.3 0.6x=6.3 x=6.3÷0.6 x=10.5 2/3x+3/4x=1 8/12x+9/12x=1 17/12x=1 x=12/17 1/4x-5%=4.8 1/4x = 4.8+0.05 1/4x = 4.85 x=4.85x4 x=19.4

1.12/(0.5x-1)=4 0.5x-1=12/4=3 0.5x=4 x=8 2.12x-3=8x+17 12x-8x=17+3 4x=20 x=20÷4 x=5 3.25.2x/3=6.3*4 8.4x=6.3*4 x=6.3*4÷8.4 x=3 4.9.8*一又二分之一-x*50%=2.4 14.7-0.5x=24 0.5x=14.7-24=-9.3 x=-9.3÷0.5 x=-18.6

x-2/5=9/14 x=9/14+2/5 x=45/70+28/70 x=73/70 x=70分之73
