Given data:

The first equation is x + 9y = 3.

The second equation is x - 4y = -10.

Subtract second equation from the first equation.

$\begin{gathered} (x+9y)-(x-4y)=3-(-10) \\ 9y+4y=3+10 \\ 13y=13 \\ y=1 \end{gathered}$

Substitute 1 for y in the first equation.

$\begin{gathered} x+9(1)=3 \\ x=-6 \end{gathered}$

Thus, the value of x is -6 and the value of y is 1.
