  1. You must learn to "translate" the English into Math

    "The product of a number and 2 has the same value as that number minus 2"
    - product means multiply
    - a number --- x

    so far: (x)(2) or 2x
    - has the same value ---> =
    so far: 2x =
    - that number minus 2 ---> x-2

    so your "English" to Math says:
    2x = x-2
    x = -2
