Find the value of x.. Guys please help me.. I have exams on Saturday and I really need help n this sum​

Answer 1

Answer:

$when \: \: divided \: the \: \: powers \: will \: be \: \: subtracted$

so we have

$\frac{ {7}^{5x - 5 - x} }{ {2}^{5x - 5 - x} } = \frac{ {7}^{3} }{ {2}^{3} }$

$it \: means$

$5x - 5 - x = 3 \\ = > 4x - 5 = 3 \\ = > 4x = 8 \\ = > x = 2$

Its the answer

Answer 2

Step-by-step explanation:

5x−5−x=3

=>4x−5=3

=>4x=8

=>x=2
