    the answer is 6x-3

    Step-by-step explanation:

    your adding 2x-1, x+5, and 3x-7

    this is done by combing like terms

    this means 2x, x and 3x get added together (remember the x has a 1 in front of it) this gives you 6x

    -1,-7, and5 are added together giving you - 3

    put that together 6x-3
