Let the number of men and the number of women in the beginning be x and y
Now,
Now, In 2nd case,
No. Of men=x-63 and no. Of women =y-12
Now,the ratio becomes
Now,we have, 2x=5y
Putting the value of Y=56 in 2x=5y,we get,
Hence, the number of men was 140 and the no. of women was 56

Answer:x=2.114
Step-by-step explanation:
Given
Let 
Taking 
both sides
X + 4 = 4x + 2
let’s put the x’s on one side and the numbers on the other
(whatever you do to one side, you have to do to the other)
x + 4 = 4x + 2
- 4 - 4x
x - 4x = 2 - 4
-3x = -2
—— ——
-3 -3
x = 2/3
to check this, we can put 2/3 in for x
(2/3) + 4 = 4(2/3) + 2
4 2/3 = 8/3 + 2
4 2/3 = 2 2/3 + 2
and there we can see both sides equal 4 and 2/3, making it true
