Answer:
a. 8x + 4y = −4
17x + 2y = −28
Step-by-step explanation:
{6x + 2y = −6
{3x − 4y = −18
{6x + 2y = −6
{1½x - 2y = −9
___________
[Plug this back into both equations above to get the y-coordinate of 3];
Alternatively, you plug the solution of into the top answer choice to get this:
{−16 + 12 = −4 ☑
{−34 + 6 = −28 ☑
These are genuine statements, therefore this system of equations is the system we are looking for.
