    No solutions.

    Step-by-step explanation:

    y = - 7x + 3

    y + 7x = 10

    Rearranging the first equation we get:

    y + 7x = 3

    Note that in the last 2 equations we have y + 7x on the left side and a 3 and 10 on the right; y + 7x cannot be equal to 3 and 10, therefore there are no solutions.
