Hi all.

I have an ext. exam coming up tomorrow and I needed help with Equations with Fractions.

I looked up a tutorial and got this, which I do not understand:

How do they multiply the terms by 15?

x

3+ x− 2

5= 6 Multiply both sides of the equation -- every term -- by the LCMThe LCM of 3 and 5 is 15. Therefore, multiply every term on both sides by 15:of denominators. Every denominator will thencancel. We will then have an equation without fractions.

Each denominator will now

15 ·x

3+ 15 ·x− 2

5= 15 ·6cancelinto 15 -- that is the point -- and we have the following simple equation that has been "cleared" of fractions:

5 x+ 3(x− 2)= 90.

Like how do they multiply 15 by x over 3?

This is confusing. :P

Thanks in advance!
