W = Women´s present age
S = Son´s present age
A women is now 3 times as old as his son means:
W = 3 S
After 10 yrs women will be W + 10 yrs old, son wil bee S + 10 yrs old.
In 10 years times, the sum of their ages will be 76 means:
W + 10 + S + 10 = 76
Replace W = 3 S in this equation:
3 S + 10 + S + 10 = 76
4 S + 20 = 76
Subtract 20 to both sides
4 S = 56
Divide both sides by 4
S = 14
Son´s present age = 14
W = 3 S = 3 * 14 = 42
Woman´s present age = 42
When her son was born woman was 42  14 = 28 yrs old 👍
