Answer:
The answer is 3
Explanation:
Let the number to be found be x
The product of a number and 3 is written as
3 × x = 3x
15 minus twice the number is written as
15 - 2x
Now equate the two statements
That's
3x = 15 - 2x
Group like terms
3x + 2x = 15
5x = 15
Divide both sides by 5
the final answer is
x = 3
