Answer:

y = x - 5 + 5

Let x be the the original position and y be the new position.

After rid down, 5 floors, the expression would be y = x - 5.

After rid back up 5 floors, the expression changed to y = x - 5 + 5.

Hence, the required expression is y = x - 5 + 5 = x.

Answer:

$x=11$

Step-by-step explanation:

Given the equation

$\log_{15}(2x-2)=\log_{15}(x+9)$

Note that

$2x-2>0\\ \\2x>2\\ \\x>1$

and

$x+9>0\\ \\x>-9$

Combined, $x>1$

Solve the equation:

$2x-2= x+9\\ \\2x-x=9+2\\ \\x=11$

Since $11>1,$ this is the solution to the equation.
