Kate is 4yrs older than Margaret . In 7yrs the sum of their ages will be 70. How old are they now. How do you find kates age using mArgarets
m = Margaret's age
m + 4 = Kate's age
m + 7 = Margaret's age in 7 yrs
m + 4 + 7 = m + 11 = Kate's age in 7 yrs
m + 7 + m + 11 = 70
2m + 18 = 70
2m = 52
m = 26
Margaret is 26
Kate is 30

To find Kate's age using Margaret's age, we can set up a system of equations based on the information given.
Let's assume Margaret's age is represented by M. According to the given information, Kate is 4 years older than Margaret, so Kate's age would be M + 4.
In 7 years, Margaret's age will be M + 7, and Kate's age will be (M + 4) + 7 = M + 11. The sum of their ages in 7 years will be 70, so we can set up the equation:
(M + 7) + (M + 11) = 70
Simplifying the equation, we have:
2M + 18 = 70
Subtracting 18 from both sides:
2M = 52
Dividing both sides by 2:
M = 26
Therefore, Margaret is currently 26 years old.
To find Kate's age, we substitute Margaret's age back into the equation:
Kate's age = Margaret's age + 4
= 26 + 4
= 30
Therefore, Kate is currently 30 years old.
