    x = 2a

    Step-by-step explanation:

    5 (bx-2ab) = b (x-7a) + 5ab

    Distribute

    5bx - 10ab = bx - 7ab + 5ab

    Combine like terms

    5bx - 10ab = bx - 2ab

    Add 10 ab to each side

    5bx - 10ab+10ab = bx - 2ab+10ab

    5bx = bx+8ab

    Subtract bx from each side

    5bx - bx = bx - bx + 8ab

    4bx = 8ab

    Divide each side by 4b

    4bx/4b = 8ab/4b

    x = 2a

    5 (bx-2ab) = b (x-7a) + 5ab

    5bx - 10ab = bx - 7ab + 5ab

    4bx = 8ab

    x = 8ab / (4b)

    x = 2a
