  • 3x(-9)+7x(-9)

    (-54)x1/6x(-1/3)x/3 -5 = (5-x)/2

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

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

    (5-2)/2 - (4+x)/3 =1

    x/3 -1 = (1-x)/2

    (x-2)/2 - (3x-2)/4 =-1

    (5y+1)+(1-y)=(9y+1)+(1-3y)

    7(2x-1)-3(4x-1)=4(3x+2)-1

    10x=11 x=-1.1

    2x+5=45

    2(x+8)=48

    88-25x=45+6x

    566+48x=56-x

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

    11x+64-2x=100-9x

    15-(8-5x)=7x+(4-3x)

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

    3x*2+27=0

    3x*2-4x-4=0.

    (2y+1)2+3(2y+1)+2=0.

    (x-2)2-3=0

    2x^2-5x+1=0

    x(8+x)=16

    (2x-3)^2-2(2x-3)-3=0

    x^2-17x+66=0

    (x+1)^2-2(x-1)^2=6x-5 4

    (x+2)^2=9(2x-1)^2
