  1. y=-(1/2)x-3=-([1/2]x+3)

    y=2x+2=2(x+1)

    Therefore through transitivity:

    -([1/2]x+3)=2(x+1)

    multiply by -1.

    [1/2]x+3=-2x-1

    Add 1

    [1/2]x+4=-2x

    Add 2x

    [5/2]x+4=0

    Subtact 4

    [5/2]x=-4

    Multiply by 2

    5x=-8

    Divide by 5.

    x=-8/5

    y=2(x+1)=2(-8/5+1)=2(-3/5)=-6/5

    Peace


  2. y=-1/2x-3, y=2x+2

    -x/2 - 3 = 2x + 2

    -5 = 5x/2

    x = -10/5

    x = -2

    y = 2*-2 + 2 = -2



    x = -2, y = -2
