    Answer:

    Here you go!

    Step-by-step explanation:

    Since we are not yet sure what our number is, we should use a variable to represent that number, and then solve for that variable.  

     

    I will use “x” as our variable to represent the number we are trying to find.  

     

    Let’s take the problem piece by piece.

     

    Six less than four times a number.

     

    If we are using x to represent our number, we know that when we do four times that number we are multiplying x times 4, which is the same as writing “4x.”

     

    Next we know that we are taking six less than 4x. Six less than means we will be subtracting 6 from our 4x, which is the same as writing 4x – 6.

     

    Finally, we know that six less than 4x (4x – 6) equals 15. Now we have a full equation:

     

    4x – 6 =15

     

    Now we have to solve for x by getting x by itself:

     

    4x – 6 = 15

    add 6 to both sides to move the 6 away from the x

    4x = 21

    now divide by 4 to get x by itself

    x = 21/4, in decimal form this is 5.25
