Question

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

Answer 1

4^x+2^2x=47

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

Answer 2

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

x=3
