Answer 2

Answer:

6 ; Option(D)

Step-by-step explanation:

$(\frac{9}{7} )^{3} *(\frac{49}{81} )^{2x-6} =(\frac{7}{9} )^{9} \\\\(\frac{9}{7} )^{3} *(\frac{7}{9} )^{2(2x-6)} =(\frac{9}{7} )^{-9} \\\\(\frac{9}{7} )^{3} *(\frac{7}{9} )^{4x-12} =(\frac{9}{7} )^{-9} \\\\(\frac{9}{7} )^{3} *(\frac{9}{7} )^{-1(4x-12)} =(\frac{9}{7} )^{-9} \\\\(\frac{9}{7} )^{3} *(\frac{9}{7} )^{(-4x+12)} =(\frac{9}{7} )^{-9} \\\\(\frac{9}{7} )^{(-4x+12+3)} =(\frac{9}{7} )^{-9} \\\\-4x+12+3=-9\\\\-4x+15=-9\\\\-4x=-9-15\\\\-4x=-24\\\\x=\frac{-24}{-4} \\\\x=6$
