Answer:
like here x= 3 and y= -15
here, its 5 times goes in negative
now if y = 10 TO X IS 5 TIME POSITIVE HERE = 10×5 = 50
<span>This is an example of the substitution property of equality, meaning that if pq = 3, you may substitute 3 for pq in another related equation. So if pq+rs=5 is true, then 3+rs=5 is true as well.</span>
