Answer:

The sum of the ages of a woman and her daughter is 46 years.

x + y = 46

or

y = (46-x)

;

In four years time the ratio of there ages will be 7:2

Cross multiply

2(x+4) = 7(y+4)

2x + 8 = 7y + 28

2x = 7y + 28 - 8

2x = 7y + 20

replace y with (46-x)

2x = 7(46-y) + 20

2x = 322 - 7x + 20

2x + 7x = 342

9x = 342

x = 342/9

x = 38 yrs is the woman's age

Answer:

age a woman=38years

the age her daughter=8years

Step-by-step explanation:

let current age of woman be---x

and current age of daughter---y

x+y=46

x=46-y--------1

(x+4)/(y+4)=7/2

2x+8=7y+28

2(46-y)-7y=20

92-2y-7y=20

9y=72

y=8

x=46-8=38
