Answer:
The correct answer is x = 3 and y = 2.
Step-by-step explanation:
There are many ways to solve systems of equations like this, but I'm going to use substitution. This means taking the value of y given by the second equation and plugging it into the first equation. This is modeled below:
2x - y = 4
2x - (-2x+8) = 4
Now, we can simplify the left side of the equation.
2x + 2x - 8 = 4
4x - 8 = 4
We should add 8 to both sides as the next step.
4x = 12
Now we can divide by 4.
x = 3
To solve for y, we can substitute this value found for x back into either one of our original equations.
y = -2x + 8
y = (-2*3) + 8
y = -6 + 8
y = 2
Therefore, the correct answer is x = 3 and y = 2.
Hope this helps!

92.49 -63.854 ≈ 92 -64 = 28
____
Actual difference is 28.636.
100.014. I think this is it
We are given numbers √9 and -7.
Square root 9 is a perfect square.
Square root 9 = 3.
So, if we add square root 9 and -7, we would get
√9 + -7 = 3 -7 = -4.
So, we got a negative whole number.
<em>A negative or positive whole number is called an integer</em>.
So, it's an integer.
<h3>Therefore, correct option is D. Integer.</h3>
