Question

p lz bro solve this math question.......spams will be reported .dont give ANswer directly​

Answer 1

$log_{5}( \frac{x}{y} ) \: = log_{5}( 4 \times 2 ) \\ \\ \frac{x}{y} = 8$

Given x - y = 7

Put y = x/8 in the equation.

We get , 7x = 56

Thus, x = 8

Mark as the brainliest if you like :)

Answer 2

The value of x is 8.

Step-by-step explanation:

The expression is:

$\log_{5}x-\log_{5}y=\log_{5}4+\log_{5}2$

Given:

x - y = 7... (*)

Solve the expression as follows:

$\log_{5}x-\log_{5}y=\log_{5}4+\log_{5}2$

            $\log_{5}\frac{x}{y}=\log_{5} (4\times 2)$

                $\frac{7+y}{y}= 8$

              $7+y=8y$

                    $7=7y\\y=1$

Substitute y in equation (*) and solve for x as follows:

x - y = 7

x - 1 = 7

x = 7 + 1

x = 8

Thus, the value of x is 8.
