LAST ONE I SWEAR BUT STILL WILL MARK BRAINLIEST

Mathematics
1 answer:
Pavel [41]3 years ago
5 0

Answer:

a. 8x + 4y = −4

17x + 2y = −28

Step-by-step explanation:

{6x + 2y = −6

{3x − 4y = −18

{6x + 2y = −6

{1½x - 2y = −9

___________

\displaystyle \frac{7\frac{1}{2}x}{7\frac{1}{2} = -\frac{15}{7\frac{1}{2}} \\ \\ x = -2[Plug this back into both equations above to get the y-coordinate of 3]; \displaystyle 3 = y

Alternatively, you plug the solution of \displaystyle [-2, 3] 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.

I am joyous to assist you anytime.
