X/6 + X/3 =3

If i make the denominator on the left 6, do I need to do the same on the right hand side?

another example is 5x/3 - 3x/4=11/6

"*X/6 + X/3 =3*

The simplest way is to multiply every term (on the RHS as well as the LHS) by the lowest common denominator of the 6 and the 3 (in this case that is just 6).

"*another example is 5x/3 - 3x/4=11/6*"

In this case multiply every term by the lcd of 3 and 4 (namely 12).
