Solve each system using elimination.<br> − 5 = −10 <br> − + = 6
Maksim231197 [3]

The values of (x, y) are (-5, 1), if the equations x-5y=-10 and -x+y=6 are solved by elimination method.

Step-by-step explanation:

The given is,

                      x-5y=-10................................(1)

                    -x+y=6.....................................(2)

Step:1

           Equation (2) is multiplied by -1 ( Eqn (2) × -1 )

                      x-y=-6..................................(3)

Step:2

         Substrate the equation (1) and equation (3),

                                      x-5y=-10

                                        x-y=-6

          ( - )

         After the Subtraction equation becomes,

                   (x-x)+(-5y+y)=(-10+6)

                                (0)+(-4y)=(-4)

                                            -4y=-4

                                                 y=1

Step:3

           By using y value find value of x,

                                  x-5y=-10

                             x-(5)(1)=-10

                                           x=-10+5

                                           x=-5

Step:4

           Check for solution,

                                  -x+y=6

                              -(-5)+1=6

                                             6=6

           Both sides are equal so answer is corrected

Result:

         The values of (x, y) are (-5, 1), if the equations x-5y=-10 and -x+y=6 are solved by elimination method.
