    This Must Only Have One Solution, Because The Right Side Of The Equation Is Just Plainly Ten. Lets Solve This:

    5x + 3x - 4 = 10

    Add Four To Both Sides To Begin Simplifying.

    5x + 3x = 14

    Now, Combine Like Terms.

    8x = 14

    Divide:

    8x/8 = 1X = X

    14/8

    X = 14/8

    14/8 = 1.75

    X = 1.75

    Check:

    (5 * 1.75) + (3*1.75) - 4 = 10

    8.75 + 5.25 - 4 = 10

    14 - 4 = 10

    10 = 10.

    This Is True, So X Does Equal 1.75
