Answer 4

@Paynesdad

Answer 5

\[\frac{3}{3x + 1} \div \frac{x + 410}{7x}\]

Reciprocate the second fraction to write the expression as the multiplication of two fractions, then simplify.

Answer 6

so i take x out of the numerator and denominator

Answer 7

i an so lost on this question

Answer 8

@helpplzzzz12120 You can't solve for x if there is no equal sign!

Answer 9

Good observation @Paynesdad

Answer 10

oh i stink with fractions like this

Answer 11

Fractions is tough for lots of students. Too many students weren't really taught well and rigorously when they should have been in like 3rd -5th grade ("because they have calculators")...and now they suffer in higher level math. I made my son learn fractions backwards and forwards when he was young so he wouldn't struggle so much when he got to higher level math.

Answer 12

@helpplzzzz12120 Still the fact remains with out an equals sign there is no way to solve for x ... check the question and see if you posted on here properly.

Answer 13

ok

Answer 14

5/(x^2-1-2(x)=2/(x+1)

Answer 15

That looks totally different!

Answer 16

\[5divx^2-1-2divx=2divx+1\]

Answer 17

I am not sure what that equation means ... bear with me. Is that \[\frac{5}{x^2-1}-2x=\frac{2}{x+1}\]

Answer 18

it loks like this accept -2 is over x

Answer 19

that*

Answer 20

Gotcha \[\frac{5}{x^2-1}-\frac{2}{x}=\frac{2}{x+1}\]

Answer 21

yes thats what it looks like

Answer 22

So what you want to do firat is factor the denominator of the first fraction so we can figure an LCD

Answer 23

Ok wish I could help more, but I have to go.

Answer 24

ok thanks

Answer 25

i got x=-3 and x=3 is that right?

Answer 26

Just plug your answer back in and check like this
