What is the solution to this system of equations?

x − 2y = 15
2x + 4y = -18

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

Step-by-step 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)
