  • 一元一次方程:

    1.2(x-2)-3(4x-1)=9(1-x)

    2.11x+64-2x=100-9x

    3.15-(8-5x)=7x+(4-3x)

    4.3(x-7)-2[9-4(2-x)]=22

    5.3/2[2/3(1/4x-1)-2]-x=2

    6.2(x-2)+2=x+1

    7.0.4(x-0.2)+1.5=0.7x-0.38

    8.30x-10(10-x)=100

    9.4(x+2)=5(x-2)

    10.120-4(x+5)=25

    11.15x+863-65x=54

    12.12.3(x-2)+1=x-(2x-1)

    13.11x+64-2x=100-9x

    14.14.59+x-25.31=0

    15.x-48.32+78.51=80

    16.820-16x=45.5×8

    17.(x-6)×7=2x

    18.3x+x=18

    19.0.8+3.2=7.2

    20.12.5-3x=6.5

    21.1.2(x-0.64)=0.54

    22.x+12.5=3.5x

    23.8x-22.8=1.2

    24.1 50x+10=60

    25.2 60x-30=20

    26.3 3^20x+50=110

    27.4 2x=5x-3

    28.5 90=10+x

    29.6 90+20x=30

    30.7 691+3x=700

    31 x+5=8

    32 3x+5(138-x) = 540

    33 x-5=3

    34 2x-10.3x=15

    35 0.52x-(1-0.52)x=80

    36 x/2+3x/2=7

    37 3x+7=32-2x

    38 3x+5(138-x)=540

    39 3x-7(x-1)=3-2(x+3)

    40 18x+3x-3=18-2(2x-1)

    41 3(20-y)=6y-4(y-11)

    42 -(x/4-1)=5

    43 3[4(5y-1)-8]=6

    44 2(x-2)+2=x+1

    45 2(x-2)-3(4x-1)=9(1-x)

    46 x/3 -5 = (5-x)/2

    47 2(x+1) /3=5(x+1) /6 -1

    48 (1/5)x +1 =(2x+1)/4
