Answer: The answer is 3n + 2
Step-by-step explanation: You will have to combine like terms:
=−n + −4 + 4n + 6
=(−n + 4n) + (−4 + 6)
=3n + 2
The Greatest Common factor is 11x^2y so the factors are
11x^2y(x^2 - 2y)
Answer:
y = -4
x = -2
Step-by-step explanation:
Hi there...
y = 2x
y = -x - 6
Since why is equal to 2x, we can plug it in for y in the second equation. Here's what I mean...
2x = -x - 6
add x on both sides...
3x = -6
divide by 3 on both sides...
x = -2
Now, plug in x for y. Here's what I mean...
y = 2x
y = 2 (-2)
y = -4
Hope this helps :)
