Well there are gonna be several ways to go about this. I honestly can't remember the "proper way" to go about this, but if you want I can explain how I got to the answer.

Well the first thing I did was make the numerators equal. Which I did by \[\frac{ 3 }{ 3 }*\frac{ 1 }{ 7 }\] Now that I had the numerators equal this is what the equation looked like.\[\frac{ 3 }{ 21 }=\frac{ 3 }{ 4x-1 }\] At this point, I set aside the numerators and focused on the denominators and wrote it out as\[21=4x-1\] Then I just solved for x

\[21=4x-1\]\[22=4x\]\[\frac{ 22 }{ 4 }=x\]Simplfy and rearrange to get \[x=\frac{ 11 }{ 2 }\]
