Question

find four solutions of the equation 3x-2y=7. how many solution can be found for this equation.

Answer 1

Given : The equation 3x - 2y = 7

To find: Four solutions of the given equation.

Solution:

• Now the given equation is: 3x - 2y = 7

• Lets put the value of x, we will get the value of y.

• So let x = 0, we get:

                 3(0) - 2y = 7

                 y = -7/2

                 (x,y) = (0,-7/2)

• Let x = 1, we get:

                 3(1) - 2y = 7

                 -2y = 4

                 y = -2

                 (x,y) = (1,-2)

• Let x = 2, we get:

                 3(2) - 2y = 7

                 - 2y = 1

                 y = -1/2

                 (x,y) = (2,-1/2)

• Let x = -1, we get:

                 3(-1) - 2y = 7

                 - 2y = 7 + 3

                 - 2y = 10

                 y = -1/5

                 (x,y) = (-1,-1/5)

Answer:

            So the four solutions are: (0,-7/2), (1,-2), (2,-1/2), (-1,-1/5) and there can be infinite solutions.
