Four less than a number equals four times the sum of a number and 2. Is this statement true for only one number, for all numbers, or for no numbers? Explain your reasoning.
If the same number is indicated in both places where the words "a number" appear, then the statement is true only when that number is -4 .
If "a number" and "a number" stand for two different numbers, then there are an infinite list of ordered pairs of numbers that make the statement true.
