1. The problem statement, all variables and given/known data http://img213.imageshack.us/img213/2327/nummer1.jpg [Broken] 2. Relevant equations 3. The attempt at a solution I find that that 3x*42x+1=4*48x and 6x+2=36x then i but ln(4*48x)=ln(48)*x+2*ln(2) and ln(36x)=2*ln(6)*x we get: ln(48)*x+2*ln(2)=2*ln(6)*x Now my proplem is; Is this all correct and what how do i move them around so i get x? I im really bad at moving those number around but x seems to dissapear for me!
