2x+4y=36 6x+2y=3 Ordered pair

Step-by-step explanation:

2x+4y=36 - equation 1

6x+2y=3 - equation 2

from equation 1,

2x + 4y = 36

2x = 36 - 4y

x = 36/2 - 4y/2

x= 18 - 2y - equation 3

insert equation 3 into equation 2

then, 6x+2y=3

therefore, 6(18 - 2y) + 2y = 3

               108 - 12y + 2y = 3

              108 -10y = 3

              108 - 3 = 10y

               105 = 10y

               y = 105/10

               y = 10.5

in solving for x, insert    y = 10.5 into equation 1

therefore, 2x+4y=36

                 2x + 4 (10.5) = 36

                 2x + 42 = 36

                2x = 36 - 42

                2x = -6

                x = -6/2

 therefore x= -3

Ordered pair, x= -3 and y = 10.5
