Question

Choose the equivalent system of linear equations that will produce the same solution as the one given below.

6x + 2y = -6
3x - 4y = -18

12x + 4y = -12
15x = -30

8x + 4y = -4
14x = -10

6x - 8y = -36
-6y = -42

6x - y = -15
3y = 9

Answer 1

Answer 2

The solution to:

\(6x + 2y = -6\)
\(3x - 4y = -18\)

is \((-2,3)\).

A and D both have the solution \((-2,3)\).

Answer 3

oh but how did you get the solution
