Hi...☺

Here is your answer...✌

$\frac{7 {}^{ 3} }{7 {}^{x - 2} } = {7}^{7} \\ \\ {7}^{3 - (x - 2)} = {7}^{7} \: \: \: \: \: \: \: ( since \: \: \frac{ {a}^{m} }{a {}^{n} } = {a}^{m - n} \: \: ) \\ \\ b y\: equating \: power \: of \: 7 \\ \\ = > 3 - (x - 2) = 7 \\ \\ = > 3 - x + 2 = 7 \\ \\ = > 5 - x = 7 \\ \\ = > x = 5 - 7 \\ \\ = > x = - 2$
