1/3x+2x=3 3/4 what does the variable represent?

Start off by combining like terms on the LHS (the terms with x in them).

So we get 

Replacing this result with what we had before on the LHS, we get 

⇒Solve for x (divide both sides )
⇒Don't forget about reciprocity rules when dividing.  This is the same as multiplying both sides by 

⇒
⇒ ***This is a proper fraction
