    B=7x

    Step-by-step explanation:

    5 (x+2) + 2 (x-5)

    5x+10+2x-10

    since 10-10=0, it just won't show, there's no need to say "0"

    5x+2x+10-10

    7x+0

    so just

    7x

    Answer:7x

    Step-by-step explanation:

    5 times x 5 times 2 = 5x + 10

    2 times x 2 times - 5 = 2x - 10

    5x + 2x = 7x

    10 - 10 = 0
