Thread: This is a Linear function

1. This is a Linear function

3(5x-4)/7 = 6(4x+3)/5
I sort of forgot how to do it.
Any help is great.

$\frac{15x-12}{7}=\frac{24x+18}{5}$ , cross multiply

$75x-60=168x+126$

$75x-168x=126+60$ .. Can continue?

3. Do what? You titled the thread, "This is a Linear function", which it is NOT- it is a linear equation-but you haven't said what you want to do with it.

Guessing that you want to solve the equation, I would suggest ,multiplying both sides by (5)(7)= 35 to get rid of those denominators. Doing that you should get 15(5x- 4)= 42(4x+ 3). Now multiply out each side: 75x- 60= 164x+ 123. Can you finish from there?
