    Yes

    Step-by-step explanation:

    5x - (7x-1) = -3x+8

    5x - 7x + 1 = - 3x + 8

    -2x + 3x = 8 - 1

    x = 7

    x=7 so there is one solution

    Step-by-step explanation:

    5x - (7x-1) = -3x+8

    Distribute the minus sign

    5x - 7x + 1 = - 3x+8

    Combine like terms

    -2x + 1 = - 3x+8

    Add 3x to each side

    -2x+3x+1 = - 3x+3x+8

    x+1 = 8

    Subtract 1 from each side

    x+1-1=8-1

    x=7
