City A is 25% less than population of city B. So city A's population is 75% of city B
<h3>
<u>Solution:</u></h3>
Given that City A is 25% less than population of city B
To find: city A's population is what % of city B
From given information,
City A is 25% less than population of city B
A = B - 25% of B
So we can write as,

A = 0.75B can be written as,

Answer:
x= 5.25
Step-by-step explanation:
You have to get x alone, so do inverse operations.
(Basically, reverse what it is)
4(x-3)=9
divide 4 by both sides to get rid of 4 on left side
9/4 = 2.25
(x-3) = 2.25
Now add 3 to both sides, to get x alone
2.25 + 3 = 5.25
x=5.25
Check work
4(5.25-3) = 9
4(2.25) = 9
9=9
