    5 (y + x) or c: 5x+y

    Step-by-step explanation:

    Simplify the following:

    9 x - 3 y - 5 x + 7 y + x + y

    Grouping like terms, 9 x - 3 y - 5 x + 7 y + x + y = (-3 y + 7 y + y) + (9 x - 5 x + x):

    (-3 y + 7 y + y) + (9 x - 5 x + x)

    -3 y + 7 y + y = 5 y:

    5 y + (9 x - 5 x + x)

    9 x - 5 x + x = 5 x:

    5 y + 5 x

    Factor 5 out of 5 y + 5 x:

    Answer: 5 (y + x)
