PLS HELP ME ASAP! FOR 15 POINTS AND DONT GIVE ME A LINK Select the correct answer.
What is the solution to this system of equations?

x − 2y = 15
2x + 4y = -18

A. x = 1, y = -6

B. x = 1, y = -7

C. x = 3, y = -6

D. x = 3, y = -7

C. x = 3, y = -6 is the answer.

Step-by-step explanation:

1. Isolate x for x = 2y = 15 -> x = 15 + 2y

2. Substitute x = 15 + 2y -> [2 (15 + 2y) + 4y = -18]

3. Simplify -> [30 + 8y = -18)

4. Isolate y for 30 + 8y = -18 -> y = -6

5. For x = 15 + 2y, substitute y = -6 -> x = 15 + 2(-6)

So, x = 3 and y = -6 are the solutions to this system of equations.

Hope this helps! :)
