Answer:
or 
Step-by-step explanation:
we know that
To find the unit rate divide 27 1/5 by 4/5
but first
Convert mixed number to an improper fraction

so

The value of x is 1.25 or 1 1/4
Explanation
==============================
275x=500-125x
Move variable to the left side and change its sign
275x+125x=500
Collect the like terms
275x+125x=500 =====> 400x=500
Divide both sides of the equation by 400
400x/400=500 =======> x=5/4 which is the same as 1 1/4 or 1.25
