I am three years younger than my brother, and i am 2 years older than my sister. My mom's age is one less than three times my brother's age. When you add all our ages, you get 87. What are our ages?

Answer 1

brother's age -- x
my age --- x-3
sisters age --- x-5
mom's age ---- 3x-1

x + x-3 + x-5 + 3x-1 = 87
6x = 96
x = 16
sub back into my defitions

Answer 2

Thank you!!! This helped a lot!

Answer 3

I'm sorry, but this answer is incorrect. It was not helpful. The 'My Age' is actually x and your equation is also incorrect.

Answer 4

This is the correct equation: (x)+(x+3)+(x−2)+3(x+3)−1=87
Please correct me if I am wrong. Thank you!

Answer 5

Also, here is the correct answer:
My age is 13
My brother's age is x+3= 13+3 = 16
My sister's age is x-2=13-2=11
My mother's age is 3(x+3)-1=3(13+3)-1=47

Answer 6

ACTUALLY
She was correct in the first place
uhm.

Answer 7

The answer is 13 I did out the math, the first answer added nine instead of subtracting that's why it was 96, not 78 (the correct one)

Answer 8

Answer 9
