Answer:
Hazel was 3 years old when Joel was born.
Step-by-step explanation:
Let x be the present age ( in years ) of Joel,
Given,
Hazel is three times as old as Joel,
Age of Hazel = 3x,
After 4 years, age of Joel = x + 4,
And, age of Hazel = 3x + 4
According to the question,
2(x+4) = 3x + 4
by distributive property,
2x + 8 = 3x + 4
By subtraction property of equality,
2x = 3x + 4 - 8
2x = 3x - 4
Again by subtraction property of equality,
-x = -4
Divide both sides by - 1
x = 4
Thus, the present age of Joel = 4,
Also, the present age of Hazel = 12,
Difference in ages = 12 - 4 = 3,
Therefore, Hazel was 3 years old when Joel was born.
Answer
Hazel was 8 when Joel was born
Step-by-step explanation:
if she's 12 right now and he's 4 then that's 3x as old. in four years she will be 16 and he will be 8. in four years she will be 2x his age. so she was 8 when he was born since that's the difference between 12 &4, 16&8
