Consider the following situation:?
2 women and 5 men can finish a work in 4 days,while 3 women and 6 men can finish it in 3 days.
Express this in a pair of linear equations in 2 variables.Also,find days taken by 1 woman to finish the work and days taken by 1 man to finish the work.
I know Jugruda!
But in my book only the equation is given as 2/w+5/m=4
3/w+6/m=3.
But I don't know why we should use 1/w and 1/m as the variables!
Please help me!

2w + 5m = 4
w = (4 - 5m)/2
3w + 6m = 3
w + 2m = 1
w = 1 - 2m
Days for a man to finish (x):
4 - 5m = 2(1 - 2m)
4 - 5m = 2 - 4m
m = 2
Days for a woman to finish:
= (4 - 5[2])/2
= (4 - 10)/2
= - 6/2 or - 3
Answer: Improbable result on women.
