2x+14y=-8. solve for y . show work


7x+14y=14. solve for y. show your work



10x+2y=20. solve for y. show your work



Answer :

y=0

2x+14y=-8.. x=-4
7x+14y=14.. x=2
10x+2y=20.. x=2
Panoyin
   2x + 14y = -8
 2x + 14(0) = -8
       2x + 0 = 8
             2x = 8
              2     2
               x = 4
         (x, y) = (4 , 0)

  7x + 14y = 14
7x + 14(0) = 14
      7x + 0 = 14
            7x = 14
             7      7
              x = 2
         (x, y) = (2, 0)

  10x + 2y = 20
10x + 2(0) = 20
    10x + 0 = 20
          10x = 20
           10     10
               x = 2
         (x, y) = (2, 0)
