# Thread: Word Problem .. is this right

1. ## Word Problem .. is this right

Four times a number increased by seven is 123. Find the number. This is what i did.

Let x be the number

4x+7=123

If i am wrong please explain what i did wrong thank you guys.

2. 4x+7 = 123... yeah you are right.

3. thanks a lot for the quick reply

4. It is worded pretty poorly as it could also mean

4(x+7) = 123

As it is four times a number increased by seven.

5. ## .....

no ur confused because 4x means for times a number thats is unknow

6. No I am correct.

Both answers can be correct depending on how you read the statement. Unless you wrote the question down wrong!

7. ## well your kind of correct but...

Your kind correct too but the problem is that its says four times a unknown number (increased) well it says increased you have to apply the addition sign.

No there is nothing wrong with the question and how i wrote is you want i can post the thread again and see what we get. I want to see if people agree with you.

9. I can agree to disagree with you. I offered an alternate answer. As, if you read it out in your head it can sound like:

Four times a (number increased by 7)

Chill out on your flaming. It is highly counter productive.

Edit: The PM you just sent me is unecessary, i'm unlikely to provide you with any response next time if you are to send such things.

10. Ross is right. This question can be interpreted in two different ways.

1:

(Four times a number) (increased by seven) is 123. Find the number.

4x + 7 = 123

4x = 116

x = 29

2:

(Four times)(a number increased by seven) is 123. Find the number.

4(x + 7) = 123

4x + 28 = 123

4x = 95

x = 23.75

Though, it is MORE likely that the 1st interpretation is the correct one due to the lack of a decimal point.
