Find the solution set for the system of equations.

9x + 5y = 28

5x + 9y = 56

The solution set for the system of equations is 1. (-5/9, 0) 2. (-1/2, 13/2), 3. (0, 11/2), 4. (3, 9/2) .

The answer to your question is 2. (-1/2, 13/2)

Step-by-step explanation:

Equation 1      9x + 5y = 28

Equation 2     5x + 9y = 56

Process

- Solve by Elimination

- Multiply equation 1 by 5 and equation 2 by -9

                   5(9x + 5y = 28)

                  -9(5x + 9y = 56)

                   45x + 25y = 140

                  -45x - 81y   = -504

                     0     -56y = -364

                                  y = -364/-56

                                 y = 13/2 = 6.5

- Find x

                     9x + 5(13/2) = 28

                     9x + 65/2 = 28

                     9x = 28 - 65/2

                     9x = -9/2

                       x = (-9/2)/9

                       x = -1/2

2.

Step-by-step explanation:

Given Equations:

         Equation:1

          Equation:2

Multiplying Equation:1 by 5 and Equation:2 by 9, gives

   Equation:3

    Equation:4

Using Elimination Method, Subtract Equation:3 from Equation:4

 or

Putting, the value of 'y' in Equation:1

Or ,
