## T of F question

Back again.

Its another transposition of formulae question that dosen't seem to be sinking in

Make x the subject:

**5(3 - x/3) = 4(x/2 + 1) The solution should be x=3**

I could only simplify it before loosing the plot

simplified to 15 - 5x/3 = 2x + 4....then tried multiplying both sides by 3, adding 5x and taking away 4 ending up with 11=11x which is obviously wrong.....would appreciate being told where I'm going wrong.

Thanks
