0.52乘以5.4x=0.64怎样解方程

0.52*5.4x=0.64 2.808x=0.64 x=0.64/2.808 x≈0.23

1x-0.64x=36 0.34x=36

9x-4x=0.64 5x=0.64 两边同时除以5 5X/5=0.64/5 x=0.032

x-0.8x=0.64 0.2x=0.64 x=3.2

解: (1一0.64)X=17.28 0.36X=17.28 X=48

x-0.64x=7.2 0.36x=7.2 x=7.2/0.36 x=20

5x+x=0.64 解:6x=0.64 x=0.64÷6 =64÷600 =8/75

x-0.76x=64 0.24x=64 x=64÷0.24 x=800/3(即:3分之800)

解:3.2x=64 x=20

(1)2(x+1.7)=9.2, 2(x+1.7)=9.2÷2, x+1.7=4.6, x+1.7-1.7=4.6-1.7 x=2.9; (2)8x-4x=0.64, 4x=0.64,, 4x÷4=0.64÷4, x=0.16; (3)2x-0.24=0.12, 2x-0.24+0.24=0.24+0.12, 2x=0.36, 2x÷2=0.36÷2 x=0.18; (4)6.2x-x=416, 5...
