Question

Write four solutions for the following equation.

2x + y = 7

Answer 1

Given equation is:
$2x+y=7$
For x = - 1, we get
$-2+y=7$
$\Rightarrow y=9$

$\therefore$ (-1, 9) is a solution.

For x = 0, we get
$\Rightarrow 0+y=7$
$\Rightarrow y=7$

$\therefore$ (0, 7) is a solution.

For x = 1, we get
$\Rightarrow 2+y=7$
$\Rightarrow y=5$
$\therefore$ (1, 5) is a solution.

For x = 2, we get
$\Rightarrow 4+y=7$
$\Rightarrow y=3$

$\therefore$ (2, 3) is a solution.

Hence, we have four solution $(-1,9),(0,7),(1,5)and(2,3)$
