Solution

The correct option is A Not a solution
Given equation: $- 2 x + y - 7 = 0$
$⟹ - 2 x + y = 7 \Rightarrow y = 2 x + 7$
Now, check for $x = - 3$ and $y = - 2$ for the solution of given equation:
We have, RHS $= 2 x + 7$
$= 2 (- 3) + 7 = - 6 + 7 = 1 \neq - 2 =$ LHS
Hence, $x = - 3$ and $y = - 2$ isn't the solution of given equation.
