2x + 4y = -18

Answer 1

C. x = 3, y = -6

Step-by-step explanation

Answer is correct from Plato

Answer 2

The answer to your question is (3, -6)

Explanation:

Data

x - 2y = 15 Equation l

2x + 4y = -18 Equation ll

Solve the system of equations by elimination

-Multiply equation l by 2

2x - 4y = 30

2x + 4y = -18

4x + 0 = 12

4x = 12

x = 12/4

x = 3

-Substitute x in equation l

3 - 2y = 15

-Solve for y

-2y = 15 - 3

- 2y = 12

y = 12/-2

y = -6

-Solution

(3, -6)
