Using a system of equations, it is found that the three consecutive even integers are -8, -6 and -4.
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the three consecutive even integers are represented by:
n, n + 2, n + 4
The first integer is two times the third, hence:
n = 2(n + 4)
2n + 8 = n
n = -8
Thus:
n + 2 = -8 + 2 = -6
n + 4 = -8 + 4 = -4
The integers are -8, -6 and -4.

Answer:
8,10,12
Step-by-step explanation:
Smallest Integer = 2x - 2
Middle integer = 2x
Largest integer = 2x + 2
All three are every
3(2x - 2) = 2(2x + 2)
6x - 6 = 4x + 4 Add 6 to both sides
6x = 4x + 6 + 4 Combine
6x = 4x + 10 Subtract 4x from both sides
6x-4x = 10 Combine
2x = 10 Divide by 2
x = 10/2
x = 5
2x - 2 = 2*5 - 2 = 8
2x = 10
2x+2 12
3*8 = 2*12
24 = 24
So the answers are correct.
the answer of this is 19.5 pounds
