All you have to do is set up this equation (3x=2x-3), since x (the unknown number) multipled by 3 (which becomes 3x) equals x multipled by 2 (which is 2x) subtracted by 3 (which makes it 2x-3), and then solve. In the end, you should get x=-3, or -9=-6–3. So there you have it.
Hereof, what is 3 less than twice a number?
Three less than twice a number is 13.
Secondly, what is 3 more than twice a number?
The number (x) in: "3 more than twice a number is 7" is what we are solving here. In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 3, you get 7. The answer above is correct, because twice 2 is 4, and 3 more than 4 is in fact 7.
“five less” than “twice a” number is “nine”.
