Answer:
1/216
Step-by-step explanation:
Move variables to one side and constants to the other
9^3x-9^2x=3
factor out 9^2x
(9^2x)(8)=3
9^2x=3/8
3^4x=3/8
3^3x=1/8
x=1/8 x 27
x=1/216
x = 1/216
Simplify the equation, like the powers.
81x + 1 = 729x - 2
Subtract 729x on both sides to balance the equation.
-648x + 1 = - 2
Then subtract 1 from both sides.
-648x = -3
Finally divide by -648, which then leaves x equal to 1/216
