Answer:
The sum of the other 4 numbers is
Step-by-step explanation:
Let
x------> the sum of 6 numbers
y-----> the sum of the other 4 numbers
we know that
-----> equation A
substitute the value of x in the equation A
I think you can solve it by
=(x^2 - y^2) *( x^2 + y^2)
= (x -y)*(x+y)*(x^2 + y^2)
Where is the rest of the question? Anyways maybe this picture will help.
Since both equations define y, they should be equivalent.
3x+7=x-9
2x+7=-9
2x=-16
x=-8
Plug x in
y=(-8)-9
y=-17
Final answer: (-8,-17)
