Answer 1

first eliminate all fractions. what can you multiply by to do this?

Answer 2

@Peter14 honestly, no idea.. can you help me with this, like show me how to solve, so I can try to solve the next one on my own? it's the only thing that helps me.. thank you so much im like about to cry

Answer 3

\[\frac{ 10 }{ 3x }+\frac{4}{3} = \frac{7+x}{2x}\]

Answer 4

multiply everything by 6x
20+8x=(7+x)3x
see how I did that?

Answer 5

@Peter14 I think so..Is that the final answer?

Answer 6

no, that's not the final answer. do you know how to take it from there? you distribute the 3x and then solve it as a quadratic.

Answer 7

one minute, switching classes...

Answer 8

@Peter14 like I said, I'm so unsure.. can you solve this for me so I can see how to apply it with the next problem? I'm so sorry for the inconvinience..
