Answer:
x = 14 and y = 6
Step-by-step explanation:
To find the solution to this problem, we plug in the values of x and y from each answer choice and simplify.
1.
- (11) + (9) = 20. 20 = 20.
- (11) - (9) = 20. 2 ≠ 8.
2.
- (9) + (11) = 20. 20 = 20
- (9) - (11) = 20. -2 ≠ 8.
3.
- (14) + (6) = 20. 20 = 20.
- (14) - (6) = 8. 8 = 8.
4.
- (6) + (14) = 20. 20 = 20
- (6) - (14) = 8. -8 ≠ 8.
Therefore, the correct answer is x = 14 and y = 6.
Have a lovely rest of your day/night, and good luck with your assignments! ♡

Btw thanks for the points
Answer:
infinite number of solutions
Step-by-step explanation:
Work with the second equation. Subtract 8x from both sides.
- 4y + 8x - 8x = -8x - 12 Collect like terms.
-4y = - 8x - 12 Divide by - 4
-4y/-4 = - 8x/-4 - 12/-4
y = 2x + 3
That is exactly the same line as the first given. There is an infinite number of solutions.
