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
