-2(a - 8) + 6a = 36
-2(a) + 2(8) + 6a = 36
-2a + 16 + 6a = 36
-2a + 6a + 16 = 36
4a + 16 = 36
- 16 - 16
4a = 20
4 4
a = 5
Answer:
The ages of the children are 6, 9 and 12.
Explanation:
Let x= the age of the youngest child.
If the oldest child is twice the age of the youngest, the age of the oldest child is twice x or 2x.
If the middle child is 3 years older than the youngest, the age of the middle child is x+3.
If the sum of their ages is 27, then
x+2x+x+3=27aaa(Combine like terms)
4x+3=27aaa
aa−3a−3aaa(Subtract 3 from both sides)
4x=24
4x4=24aaa(Divide both sides by 4)
