Since no base is stated, assume base 10
remember
loga-logb=log(a/b)
also
log_a(b)=c translates to a^c=b
and log(a^z)=zlog(a)

log25x-log5=2 means
log_{10}(25x)-log_{10}(5)=2 translates to
log_{10}( \frac{25x}{5} )=2 simplies to
log_{10}(5x)=2 translates to
10^2=5x expands to
100=5x
divide both sides by 5
20=x

Answer:

<em>( - 10, 30 ) </em>

Step-by-step explanation:

A( x_{1} , y_{1} ) , B( x_{2} , y_{2} )

Coordinates of midpoint are

( \frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )
