    This equation is invalid, the left and right sides are not equal, therefore there is no solution.

    Step-by-step explanation:

    Simplifying

    5 + - 4 + 7x + 1 = 7x + 1

    Reorder the terms:

    5 + - 4 + 1 + 7x = 7x + 1

    Combine like terms: 5 + - 4 = 1

    1 + 1 + 7x = 7x + 1

    Combine like terms: 1 + 1 = 2

    2 + 7x = 7x + 1

    Reorder the terms:

    2 + 7x = 1 + 7x

    Add '-7x' to each side of the equation.

    2 + 7x + - 7x = 1 + 7x + - 7x

    Combine like terms: 7x + - 7x = 0

    2 + 0 = 1 + 7x + - 7x

    2 = 1 + 7x + - 7x

    Combine like terms: 7x + - 7x = 0

    2 = 1 + 0

    2 = 1

    Solving

    2 = 1
