Answer:

x = -1/2

Step-by-step explanation:

9^x + 78 = 3^(2x+3)

3^2x - 3^(2x+3) = 78

3^2x(1-3^3) = 78

3^2x(-26) = 78

3^2x(-1) = 3

-3^2x = 3

-2x = 1

x = -1/2

Answer:

X=1/2

Step-by-step explanation:

Let us take X=Y to avoid confusion with multiplication sign

9^Y + 78 = 9^Y x 27

26 x 9^Y = 78

9^Y = 3

Y=X=1/2 Answer
