Question

700 + 10b + c = 800 – 45; c = ______ b = ______, ...

Answer 1

Answer:

By solving the equation in the last we get

                                     10b + c = 55

           Therefore , there are many ordered pairs of b and c.

                   (1)  b = c = 5

                   (2) b = 6 , c = -5

                   (3) b = 4 , c = 15

                    and so on .................................................
