Question

Deborah is x years old and Sarah is 15y years old. The sum of their age is 58. If Deborah is 4 younger than Sarah, find the age of both women

Answer 1

Answer:

Deborah = 27

Sarah = 31

Step-by-step explanation:

According to the question,

                             x + 15y = 58 ----(i)

                             x - 15y = -4   ----(ii)      [∵ 15y - 4 = x]

                                                   

                                2x = 54

                              ∴ x = 27

Now, inputing the value of x in (i) equation.

                                27 + 15y = 58

                           or,  15y = 58-27

                             ∴  15y = 31
