Question

please help me solve this' 2x − 4y = 6 2x + 4y = -10 (-1, -4). (-1, -2). (2, 4). (1, -2).

Answer 1

Answer:

            (-1, -4)

Step-by-step explanation:

2x − 4y = 6   ⇒   2x = 4y + 6

2x = 4y + 6     and    2x + 4y = -10

so:  4y + 6 + 4y = -10

        4y + 6 = -10

         4y = -16

          y = -4

2x = 4(-4) + 6 = -8 + 6 = -2  

2x = -2   ⇒  x = -1
