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 $x=\frac{ 11 }{ 2 }$
