E.2
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
these are some weakness on these questions.
To solve this problem, let's break it down step by step:
1. Let's assume the unknown number is represented by the variable "x".
2. The problem states that the product of "x" and 2 is equal to "x" minus 2.
Mathematically, this can be written as: 2x = x - 2.
3. To solve for "x", let's isolate the variable on one side of the equation.
Subtracting "x" from both sides of the equation, we get: 2x - x = -2.
Simplifying, we have: x = -2.
4. Now we have determined that "x" is equal to -2.
5. Comparing this answer with the options given, the correct answer is B, -2.
Therefore, the number that satisfies the conditions stated in the problem is -2.
