Three times a number is three more than twice the number. Which equation can be used to find the value of x, the unknown number? 3x = 3 2x x = 3 2x 3x 3 = 2x 3x = 3 2 x.
We can begin by assigning a variable to the unknown number; in this case a number. Let's call this unknown number x (as that is the variable that the answer choices are given in terms of). Once we have our variable, we can begin to translate the written problem into numbers.
"Three times a number" implies multiplication of x by 3. "is" indicates an = sign. "three more" implies addition of 3. "twice the number" can be translated to multiply x by 2.
