Can any one solve this MATH problems???

Question

Can anyone answer this and tell me how you did it?

Andy's age is 2X his brother's age -3 years. If Bills age is X years how old is Andy?

Answer 1

Nope, no one can solve that problem. We do not know if Bill is Andy's brother.

Answer 2

Yes, this is a very badly worded problem. You also say that Andy's age is 2x his brother's age - 3 years. If the 3 years refers to Andy's age, then that is your answer. Andy is 3 years old. If 3 years refers to his brother's age, then Andy is 6 years old. The answer is in plain sight but the problem is so unclear that it's difficult to identify the brother's age. Bill means nothing in this problem.

Answer 3

Your wording here is a little confusing because you're using "X" to mean both "times" and a variable X, but I think I know what you're trying to say.

So X is Bill's age. Let A be Andy's age. Just translate the words to equations. "Andy's age is two times his brother's age, minus three years" means A = 2*X - 3. We're not told what Bill's actual age is, so that's all we can say Andy's age is: 2*X - 3.

Answer 4

x=2x or 1x= 2x because the 1 is assumed if a letter is alone.
1x/x=2x/x divide by x
1=2x
1/2=2x/2 divide by 2 to get the x alone to solve for it.
1/2 = x so bill is 1/2 or 6 months old

andy 2x so mult. by 1/2 2(1/2)= 1 andy is 1 yr old

Answer 5

Answer 6

Andy's age = (andy's brothers age) x 2

Answer 7

Is Bill Andy's brother?

Answer 8

2X-3 years assuming bill is his brother.

Answer 9

Your problem is not stated clearly.

Also, there doesn't appear to be enough information to solve it as is.

Answer 10

2X-3
