Exercise condition:

3 m.

1.

$x = 5, y = 2$ is a solution of the linear equation

$5x + 2y = 7$
$5x + y = 7$
$x + y = 7$
$x + 2y = 7$

2. If a linear equation has solutions

$(–2, 2), (0, 0)$ and

$(2, –2)$ , then it is of the form

$x + y = 0$
$–2x + y = 0$
$–x + 2y = 0$
$y – x = 0$

3. If we multiply or divide both sides of a linear equation with a non-zero number, then the solution of the linear equation.
