Question

2x +7y=18 find four solutions

Answer 1

Answer: hey friend here is your answer ...

2x + 7y = 18

1)Let y = 0

2x + 7(0) = 18

        2x  = 18

          x  = 18/2

         x   = 9

2)Let y = 2

2x + 7(2) = 18

2x  +  14  = 18

         2x  = 18 -14

           x  = 4/2

           x  = 2

3)Let y = 4

2x + 7(4) = 18

2x + 28 = 18

      2x    = 18 -28

        2x  = -10

          x  = -10/2

          x  = -5

( x, y) = (9 , 0) ; (2,2) ; (-5,4)

Hope it helps you ...
