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?

Question

3x = 3 + 2x
x = 3 + 2x
3x + 3 = 2x
x + 3 = 2x

Answer 1

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. 

 

Adding all of these together we get 3x = 3 + 2x. 

Answer 2

3x = 3 + 2x

Three times a number is 3x

is three more than means = 3+

twice the number is 2x
