Answer: 44
Step-by-step explanation:
Let your age be x.
Then your mother's age will be 2x + 12.
After 8 years,
Your age will be x + 8.
Your mother's age will be 3(x + 8) - 20 = 3x + 24 - 20 = 3x + 4.
This is equal to 2x + 12 + 8 = 2x + 20
2x + 20 = 3x + 4
3x - 2x = 20 - 4
= x = 16
Answer:
13/7
X + 1/7 = 2
X = 2- 1/7
x = 13/7
