The product of a number and 3 is 6 more than the number which equation models this sentence

3x = 6 + x

Step-by-step explanation:

We can express the product of a number and 3 as:

3x

Where x is the number that we don't know.

Now it says that that product is 6 more than the number (x) so we can write it down:

3x (The product of a number and 3) = (is) 6 + x (6 more than the number)

3x = 6 + x
