Answer:
2n-12=7n-15
Step-by-step explanation:
I hope i did it right im sorry if i didnt! in the first sentence it tells you "twelve less than" therefore its telling you that you are going to be subtracting which automatically means that its not going to be the first thing you write down. You then continue reading and it tells you "2 times a number (n)" which is written as 2n because to things side by side like that signifies that you are multiplying. Then you have your equal sign which is self explanatory. and basically you follow the same reasoning as you did the first part and you end up with 7n-15 and the other half of your equation. I hope that helped!

Answer: He is not correct
Step-by-step explanation:
Well to determine whether he is correct find 20% of the basic computer computer and add it to its price to determine if it equals 490 euros
20% * 400 = 80

400 + 80 = 480
480 ≠ 490
He is wrong
