    Step-by-step explanation:

    y = - 3x + 10

    3x + y = 5

    Substitute the first equation into the second equation

    Let every instance of y in the second equation be replaced with - 3x+10

    3x + (-3x+10) = 5

    Combine like terms

    10 = 5

    This is never true so there are no solutions

    (These are parallel lines with the same slope but different y intercepts)
