2. Relevant equations

3. The attempt at a solution

I find that that 3^{x}*4^{2x+1}=4*48^{x}

and 6^{x+2}=36^{x}

then i but ln(4*48^{x})=ln(48)*x+2*ln(2)

and ln(36^{x})=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!
