plz koi iska answer bata dijiye plz​

Answer 1

Four solutions for $2x+y=7$

$2x + y = 7 \\ 2x = 7 - y \\ x = \frac{7 - 2}{y}$

For every value of x, depends on y

1. Let y = 0,

then x = 0

2. Let y = 1

then x = 5

3. Let y = 5

then x = 1

4. Let y = -1

then x = -5

four solutions are : (0,0), (5,1), (1,5), (-5,-1)

the graph is in the picture.

Answer 2

The four solutions of the equation 2x + y = 7 are (0, 7), (1, 5), (2, 3) and (-1, 9). (0, 9) is the solution. (1, 9-π) is the solution. (2, 9-2π) is the solution.
