1. Answer:

   b.2,-5

   Step-by-step explanation:

   I assume y is missing in the first equation, and the correct system is:

   3x – 4y = 26

   2x + 8y = -36

   Rewrite the first equation. Divide both sides of the second equation by 2 and write it below the first equation. Then add the equations.

       3x – 4y = 26

     –   x + 4y = -18

   ————————

        4x        = 8

   x = 2

   Now substitute 2 for x in the first original equation and solve for y.

   3(2) – 4y = 26

   -4y = 20

   y = -5

   Answer: (2, -5)
