Answer:
Here's a rainbow of logic.
Step-by-step explanation:
So for this, I will be doing the elimination method. Firstly, multiply both sides of the first equation by 2:

Next, add the two equations together to get
. From here you can solve for x.
For this equation, just divide both sides by 8 and your first answer will be 
Now that we have the value of x, substitute it into either equation to solve for y:

<u>In short, the solution is (2,-5), or A.</u>
Answer:
451, 551, 651, 751, 851, 951, 1051, 1151,
Step-by-step explanation:
you're adding 1 each time you progress through the pattern. Btw pls rate me BRAINLYIEST im in 8th grade.
G^2+2=0,
g^2=-2
g= sqrt-2, not possible.
3g+1=0
3g=-1
g=-1/3
9 cannot be equal to zero for the last one.
