Simultaneous equation:
x + y = 58
x = y - 4
Substitute x in the first equation:
y - 4 + y = 58
2y = 62
y = 31
Substitute y in the second equation:
x = 31 - 4
x = 27
Therefore, Deborah is 27 years old and Sarah is 31 years old.
Deborah is x years old and Sarah is y years old. The sum of their age is 58. If Deborah is 4 years younger than Sarah. Find the age of both women
