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

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.

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!

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

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)
