Question

Solve this system of equations. Write the answer as an ordered pair.

-2x + 6y = 6

-7x + 8y = -5

Answer 1

{ - 2 x + 6 y = 6   * ( 7 )
  - 7 x + 8 y = -5  * ( - 2 )

-  14 x + 42 y = 42
   14 x - 16  y = 10
-------------------------
            26 y = 52
              
                 y = 52 / 26
          
                 y = 2

For x :

- 2 x + 6 y = 6

- 2 x + 6 * ( 2 ) = 6

- 2 x + 12 = 6

- 2 x = 6 - 12

- 2 x = - 6  * ( - 1 )

2 x = 6

x = 6 / 2

x = 3

( x , y ) = ( 3, 2 )

hope this helps!
