6x%0.5x=0.33×10 解方程计算

6x-0.5x=0.33*10,(6-0.5)X=3.3,5.5X=3.3,X=3.3÷5.5,X=0.6.

6x-0.5x=0.33X105.5x=3.3x=3.3/5.5x=3/5x=0.6(这一步可要可不要)

6x-0.5x=99 解:(6-0.5)x=99 5.5x=99 X=99÷5.5 X=18

410-3x=170 3(x+0.5)=21 0.5x+8=43 6x-3x=18 (200-x)÷5=30 (x-140)÷70=4 0.1(x+6)=3.3*0.4 4(x-5.6)=1.6 7(6.5+x)=87.5 (27.5-3.5)÷x=4

(1)6x0.5x=99 5.5x=99x=99÷5.5x=18(2)9x3*1.6=72.69x-4.8=72.69x=72.6+4.89x=77.4x=77.4÷9x=8.63)8x+4.5*3=53.5 8x+13.5=53.58x=53.5-13.58x=40x=40÷8x=5(4)3(x+1.9)=7.8x+1.9=7.8÷3x+1.9= 2.6x=

解:原式等于:6x=6.5-0.5*96x=2x=2÷6=1/3 (就是三分之一)

(1) 3:8=15:X (2) 4X=70*5 (3) 3X-21*2=60 (4) 6X+3X=270 (5) 3.6除以5X=0.2 (6) X:22.5=3.6:1.5 (7) 1.5X+1.1=3.8 (8) X-4.4*5=16 (9) 12:X=60:50 (10) 3:15=9:X [解方程] [简便计算] (1) 13.71+4.375+9.29+5.625 (2) 8.3*0.8+8.2*8.3+8.3 (3) 4.5/[(0.5

设个位上数字是x,则十位上数字是0.5x,这个数是0.5x*10+x=6x对调,各位上0.5x,十位上x,新数字是x*10+0.5x=10.5x列方程:10.5x=6x*3-2 解得x=4/15.. 答案不和题意..这题没答案的..

x=4就是了

1) 3x-(1/2 1/4)=7/12 3x=7/12 3/4 3x=4/3 x=4/9 (2) 6.6-5x=3/4-4x 6.6-0.75=-4x 5x x=5.85 (3) 1.1x 2.2=5.5-3.3x 1.1x 3.3x=5.5-2.2 4.4x=3.3 x=3/4=4/3 还有 (0.5 x) x=9.8÷2 2(x x 0.5)=9.8 25000 x=6x 3200=450 5x x x-0.8x=6 12x-8x=4.8 7.5*2x=15 1.2x
