Answer:
see explanation
Step-by-step explanation:
the 3 consecutive even integers are x , x + 2 and x + 4 , then their sum is
x + x + 2 + x + 4 = 72 , that is
3x + 6 = 72 ( subtract 6 from both sides )
3x = 66 ( divide both sides by 3 )
x = 22
x + 2 = 22 + 2 = 24
x + 4 = 22 + 4 = 26
the 3 consecutive even integers are 22, 24 , 26
x = 23
Add 20 to both sides of the equation
x-20=3
−20+20=3+20
Simplify
Solution:
x= 23
No solution
No possible values could add up to these values. If you solve the system of equations. You will get 0 = 10, meaning its impossible.
