Answer:

Solution is:

x ≈ 2.25

Step-by-step explanation:

The solution of the equation [tex]3^{-x + 2} = 2^x - 4[/tex] is that point on the graph at which the two graphs i.e. graph of [tex]3^{-x + 2}[/tex] and [tex]2^x-4[/tex] meet

As we can clearly see the two graphs meet at:

(2.251,0.759)

Hence, Solution is:

x ≈ 2.25
