    3x-5y=5

    First, subtract 3x from both sides,

    -5y=3x-5

    Second, divide everything by 5, to get y by itself

    y=-3x/5-1

    Now that we know what y equals, just substitute that for y.

    3x-5 (-3x/5-1) = 5

    Do the math ...

    3x+3x+5=5

    Add like terms ...

    6x+5=5

    Subtract 5 from both sides, then solve for x.

    6x=0

    6/6=0/6

    x=0/6=0

    So now that we know x=0, substitute 0 for x, then solve for y.

    3 (0) - 5y=5

    -5y=5

    -5/5=5/-5

    y=-1

    Since x=0 and y=-1, the ordered pair is (0,-1)
