If twice

If twice the age of the daughter is added to the age of the mother, the sum is 56. but if twice the age of the mother is added to the age of the daughter, the sum is 82. find the age of the mother and daughter.

Correct result:

d =  10
m =  36

Solution:


2d+m=56
2m+d=82

2•d+m=56
2•m+d=82

2d+m = 56
d+2m = 82

d = 10
m = 36
