help with this problem

I would like help with this problem.

7 + 3 = 5
____
2x^2

I'm assuming you multiply each part with 2x^2. Is that correct?

If you had previewed your post, you would have discovered that we cannot "draw" fractions at this site (unless we use BBCode tags).

It's easier to type ratios using grouping symbols to clearly show what belongs in numerators versus denominators.

Which of the following matches your exercise?

7/(2x^2) + 3 = 5

7 + 3/(2x^2) = 5

7 + 3 = 5/(2x^2)

(7 + 3)/(2x^2) = 5

And, YES, we could start solving for x by multiplying each term by 2x^2 (to "clear the fraction").

Sorry. When I previewed my post it didn't show the fraction like the way it turned out. The first problem you posted out of the four sample questions was the correct one. Thank you for your help.

Since that's 7 / (2x^2) + 3 = 5, then simplify first: 7 / (2x^2) = 2 ;
now do the multiplying ... get my drift?
