Answer 1

is anybody there?

Answer 2

r u sure this r the options? no of them seem to fit

Answer 3

yes I go it. thanks though

Answer 4

oh ook

Answer 5

can you check my next answer?

Answer 6

Solve the system using elimination.

3x + 3y = –9
3x – 3y = 21
A. (3, –6)

B. (–5, 2)

C. (3, 3)

D. (2, –5)

Answer 7

@doubledrive there is an answer for the first one...

Answer 8

is D (2,-5) calcmathlete

Answer 9

3x + 3y = -9
3x - 3y = 21
______________ Just add them,
6x + 0y = 12
6x = 12
x = 2
Now that you have x, which is 2, plug 2 back in one of the equations.

3(2) + 3y = -9
6 + 3y = -9
-6 -6 Subtract six from both sides.
3y = -15
y = -5
Now you have both x and y, just write them both as coordinates, (2,-5)
