    x = - 5/7

    Step-by-step explanation:

    8 / (x+3) = 1 / (x+1)

    Using cross products

    8 * (x+1) = 1 * (x+3)

    Distribute

    8x+8 = x+3

    Subtract x from each side

    8x-x + 8 = x+3-x

    7x + 8 = 3

    Subtract 8 from each side

    7x+8-8 = 3-8

    7x = - 5

    Divide by 7

    7x/7 = - 5/7

    x = - 5/7
