x/5=25 How would I find x?

hero (hero):

Hint: Multiply both sides by 5 to isolate x.

OpenStudy (anonymous):

wait...multiply 5 and 25?

hero (hero):

Yup

OpenStudy (anonymous):

but i get a really big number?

hero (hero):

As you should

OpenStudy (anonymous):

but the big number isn't one of my answers

hero (hero):

What did you get for this "big number"?

OpenStudy (anonymous):

3,125

hero (hero):

That's way too big

hero (hero):

Try multiplying 5 x 25 again

OpenStudy (anonymous):

ii did 5*5 and 25 *5. oh ... I got 125

OpenStudy (anonymous):

but that isn't one of the answers. the answers are 0.25 4 10 100

hero (hero):

None of those answer choices will work. Did you write down the problem correctly? Double-check.

OpenStudy (anonymous):

oh wow, I'm stupid! it's x/5=20 Sorry :/

OpenStudy (anonymous):

so 20 * 5 then is the answer
