How heavy is a turkey that weighs 5 pounds less than another turkey that is three times the weight of the first turkey?

2. Let a be the weight of the first turkey, b be the weight of the second turkey

$a=b-5$

$b=3a \implies a = 3a-5 \implies 2a = 5$

$a = \ldots$

3. Turkey A weighs $x$ pounds.

Turkey B weighs $3x$ pounds (since weghs 3 times the weight of turkey A.

Turkey A weighs 5 pounds less than turkey B, so

$x=3x-5$ solving that equation you get both turkeyīs weight...

so the answer is ...x= 3x-5..?

Whether the variable is a or x it doesn't matter. Both are right.

6. No, that's not the final answer. You have to solve for x.

7. No, you have to find X from the equation.
Do you know how??
Nobody wants to tell you because itīs too easy...

8. ## ?

no i dnt knw how to do it im in 7th grade and i love math my teacher gave me this as a bonus question on a test knowing we hadnt learn this yet and now i really want to learn how to do it

9. ok, so letīs do it....

$x=3x-5$
$5=3x-x$
$5=2x$
$5/2=x$

Your turkey weighs 2 and a half pounds.

Itīs your teacher who should teach you that, not us. She gets paid for it, we donīt...

Of course. It's not a problem if you make a mistake like that.

I suggest you have your teacher run through this with you. It seems you don't know anything about solving equalities yet. Let him/her do the basics with you and we should be able to assist further.

15. Exactly.
Teaching 1st degree equations must be one of the hardest things to do...

babyx0dolx, I made a little mistake and I edited my post: the answer is 5/2 pounds which is the same as two and a half pounds (2.5 pounds, if you like it).
