    Answer:

    The equation is invalid.

    Step-by-step explanation:

    Simplifying:

    28 + 8x = 8(x + 3) + 2

    Reorder the terms:

    28 + 8x = 8(3 + x) + 2

    28 + 8x = (3 * 8 + x * 8) + 2

    28 + 8x = (24 + 8x) + 2

    Reorder the terms:

    28 + 8x = 24 + 2 + 8x

    Combine like terms: 24 + 2 = 26

    28 + 8x = 26 + 8x

    Add ‘-8x’ to each side of the equation.

    28 + 8x + -8x = 26 + 8x + -8x

    Combine like terms: 8x + -8x = 0

    28 + 0 = 26 + 8x + -8x

    28 = 26 + 8x + -8x

    Combine like terms: 8x + -8x = 0

    28 = 26 + 0

    28 = 26

    Solving:

    28 = 26

    The left and right sides are not equal! Meaning theres no solution.
