15 years age cynthia was thrice as old as brittany. the sum of their present ages is 94 year. how old is brittany now

Answer 1

Answer:

31 year

Step-by-step explanation:

Let brittany age now = B

15 Year ago brittany age = B-15

Cynthia age now = 94 - B

Cynthia age 15 year ago = 94-B-15 = 79 - B

79-B = 3* (B-15)

79 - B = 3B -45

4B = 124

B = 31
