Answer:
the oldest sibling is 12 years old.
The middle child is 9 years old.
The youngest child is 6 years old.
Step-by-step explanation:
Let the age of the youngest child be x
Then the oldest child will be 2x.
The middle child will be x + 3.
Since the combined age is 27;
x + 2x + x + 3 = 27
4x = 27 - 3
x = 24 / 4
x = 6
now 2x = 12 and x + 3 = 9
Step-by-step explanation:
2×10,000 + 8×1000 + 5×100+6×10+1
2x-2y=10
Y=-5.5
Sub y into the equation and solve for x
2x-2(-5.5)=10
2x+11=10
2x=10-11
2x=-1
X=-1/2
