[tex]27^{2}[/tex] x - 6 = [tex]3^{9}[/tex] + 6
First, Evaluate the power:
[tex]27^{2}[/tex] x - 6 = [tex]3^{9}[/tex] + 6
729x - 6 = 19683 + x
Next, move the variable to the left side and change it's sign, then the constant to the right side and change its sign:
729x - 6 = 19683 + x
Next, collect like terms and add the numbers:
729x - x = 19683 + 6
728x = 19689
Finally divide both sides of the equation by 728 (any expression divided by itself equals 1):
x = 19689 / 728
x = 27 [tex]\frac{33}{728}[/tex]
