    Answer:

    Simply

    1 – x = 16 – 4x when the x is 5:

    Substitute x for 5, by replacing x with 5.

    1 – (5) = 16 – 4(5)

    1 – 5 = 16 – (4 * 5)

    1 – 5 = 16 – 20

    -4 = -4

    LHS – RHS

    It is better to show this by doing each side individually – Left Hand Side (LHS) and Right Hand Side (RHS).

    LHS

    1 – x when x = 5

    1 – 5 = -4

    RHS

    16 – 4x when x = 5

    16 – 4(5) = 16  – 20 = -4
