The answer must be -52 because I added parenthesis around -3 × 6 so it won't confuse people. I multiplied -3 and 6 and got -18. Then I multiplied -18 and 3 and got -54. I add -54 and 2 and got -52. Since there's more of negative than positive, I subtracted and got -52. Hope this helps :)

Answer:
<em>A. (1, 2)</em>
Step-by-step explanation:
8x+4y=16
7y=15-x
Divide both sides of the first equation by 4.
2x + y = 4 Eq. 1
Solve 2nd equation for x.
x = 15 - 7y
Substitute x of Eq. 1 with 15 - 7y.
2(15 - 7y) + y = 4
30 - 14y + y = 4
30 - 13y = 4
-13y = -26
y = 2
Substitute 2 for y in Eq. 1.
2x + 2 = 4
2x = 2
x = 1
Solution: (1, 2)
Answer: A. (1, 2)
Answer: x=6 and y=4
