    xe^x
    x^2-4x+20
    2(x-2)-8(x-1)=3(1-x)
    (x-20)*(800-10*x)=8000
    91.2+(20-x)*4.3=(50+226.6+6.5x)/1.5
    134.4+(23-x)*4.3=(50+226.6+6.5x)/1.5
    x*(35-2*x)=150
    3x+1=x-7
    2*x*(35-2*x)=150
    2x-(x+10)=5x+2(x-1)
    4x-3(20-x)+4=0
    x/5-(3-2x)/2=x
    x/5-3-2x/2=x
    x-3-2x =x
    X-2.1x=-100
    (100+x)/x=2.1
    (x-0.87)*300= 1200
