    x2-2x-3=0
    x2=4
    0 = x^6-17*x^4-12*x^3+49*x^2+48*x-13
    3.5(1-2x)=2. 1
    (x^2)/16+x-81/36=0
    2/3x÷1/4x=12
    2/7 x+1/2 x等于11
    18+9*0.4=1.8x
    18+0.4x=1.8x
    18+4x=1.8x
    x^2=(1+x)*(1+x)
    2-632*x^(5/3)=x
    15/133.58+x/1000+(62-x)/1650=0.136
    2x+2000÷7x-2000=5÷7
    (1+r)^2=(1+r)(1+r)
