    -3x + y > 6 is equal to y > 3x + 6 is equal to y > 3(x+2)
    so, all pairs of type ( x, y ) where y > 3(x+2) are solutions

    4x - 5y + 20 < 0 is equal to 4x < 5y - 20 is equal to x < (5/4)y - 5 is equal to x < 5( (1/4)y - 1 )
    so, all pairs of type ( x, y ) where x < 5( (1/4)y - 1) are solutions

    hope that helps
