    y=-5/11 and x=-23/11

    Step-by-step explanation:

    We can use the elimination method

    We have

    2x-7y = - 1 and

    3x - 5y = - 4

    We can multiply the first equation by 3 and the second by 2. This gives us

    3 (2x-7y) = - 1 (3) and

    2 (3x - 5y) = - 4 (2)

    Distributing and simplifying results in

    6x-21y=-3 and

    6x-10y=-8

    Subtracting the second equation from the first, we get

    0x-11y=5

    -11y=5

    y=-5/11

    putting this into the first equation, we get

    2x-7 (-5/11) = -1

    2x+35/11=-1

    x = (-1-35/11) / 2

    x=-23/11
