Question

2. If (2,4) is the solution of 2x + 4y =8.​

Answer 1

Answer:

Answer:

If we put x = 0, then y = - 2

If we put x = 1, then y = - 2/3

If we put x = 2 then y = - 1

Step by step explanation:

Given:

Equation - 2x - 4y = 8

To Find:

Three different solutions.

Now, for finding different solution of a equation we have to assume a value of 'x' and put into equation. By putting we obtain value of 'y'.

Case 1). Let x = 0

=> 2x - 4y = 8

=> 2(0) - 4y = 8

=> 0 - 4y = 8

=> y = -2.

___________________________

Case 2). Let x = 1

=> 2x - 4y = 8

=> 2(1) - 4y = 8

=> 2 - 4y = 8

=> - 4y = 6

=> y = - 4/6

=> y = - 2/3

____________________________

Case 3). Let x = 2

=> 2x - 4y = 8

=> 2(2) - 4y = 8

=> 4 - 4y = 8

=> - 4y = 4

=> y = - 1.

_____________________________

Hence, Solution of given equation are:

If we put x = 0, then y = -2

If we put x = 1, then y = -2/3

If we put x = 2, then y = -1.
