We are given –

x =9 y = -3

Now put the values –

$\qquad$ $\twoheadrightarrow\bf x - 9y - 3x + 6y -13$

$\qquad$ $\twoheadrightarrow\sf 9 -(9 \times -3) -(3 \times 9) +(6 \times -3) -13$

$\qquad$ $\twoheadrightarrow\sf 9 + 27 -27 -18 -13$

$\qquad$ $\twoheadrightarrow\sf 9 +\pink{\cancel{27}}-\pink{\cancel{27}} -31$

$\qquad$ $\twoheadrightarrow\bf-22$

Henceforth, value of x - 9y - 3x + 6y -13 is -22.
