Answer:
3^6-4x=3^3x-3
Explanation:
9^3-2x = 27^x-1 ( 9 is 3² and 27 is 3³)
(3²)^3-2x= (3³)^x-1 in case of exponential between brackets , multiply the exponents.
x = 9/7
Step-by-step explanation:
9^3-2x = 27^x-1
(3^2)^3-2x = (3^3)^x-1
3^2(3-2x) = 3^3(x-1)
2(3-2x) = 3(x-1)
2(-2x+3) = 3x - 3
-4x + 6 = 3x - 3
-4x = 3x - 9
-7x = -9
x = -9/-7
