Answer:
y = 4
x = -16
Step-by-step explanation:
this time we should multiply the first equation with -1 because we only need to change its state of negativity
2x + y = -28
-2x - 2y = 24 ➡ -y = -4 ➡ y = 4
if 2x + y = -28 the 2x + 4 =-28 ➡ 2x = -32 x = -16
Answer:
its D

Step-by-step explanation:
Look at the picture.
Hello there, and thank you for posting your question here on brainly.
Since we know what both of the exponents are, we can rewrite the equation for it.
3 * 2 - (-4)
We can evaluate from here.
I can see we have a positive number subtracting a negative number.
Use the rule where x - (-y) = x + y
2 * 3 + 4
Now we can get solving.
2 * 3 ==> 6
6 + 4 ==> 10
10 is the final answer.
Hope this helps! ☺♥
