Solution

The correct option is B $x + y = 7$
Given
$x = 5$ , $y = 2$
$x + y = 5 + 2 (2) = 9$
$5 x + 2 y = 5 (5) + 2 (2) = 29$
$x + y = 7$
$5 x + y = 5 (5) + 2 = 27$
$x = 5, y = 2$ is solution of $x + y = 7$

\frac{2}{x + 2 y} + \frac{1}{x - 2 y} = \frac{- 5}{7}

\frac{x}{y} = \frac{2 (10 y - 7)}{(5 x - 21)}

\frac{y + 7}{5} = \frac{2 y - x}{4} + 3 x - 5

\frac{7 - 5 x}{2} + \frac{3 - 4 y}{6} = 5 y - 18
