What the freak is this 4^ (x) - 2^ (x+1) = 48

4^x+2^2x=47

Step-by-step explanation:

4^x+2^2x+1=48

We move all terms to the left:

4^x+2^2x+1 - (48) = 0

We add all the numbers together, and all the variables

4^x+2^2x-47=0

We move all terms containing x to the left, all other terms to the right

4^x+2^2x=47

4^x - 2^ (x+1) = 48

x=3
