Asked by Kendall

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?

Answers

Answered by Reiny
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

Thank you!!! This helped a lot!

I'm sorry, but this answer is incorrect. It was not helpful. The 'My Age' is actually x and your equation is also incorrect.
Answered by Mildred
This is the correct equation: (x)+(x+3)+(x−2)+3(x+3)−1=87
Please correct me if I am wrong. Thank you!
Answered by Mildred
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

uhm.
Answered by No
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)
