$(underlinecolor(red)3,11)$ is a solution to $6x-y=7$

Explanation:

Note I have used the letter $a$ in place of the underscore from the original version of the question.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If $(color(red)x,color(blue)(y))=(color(red)a,color(blue)(11))$
is a solution to $6color(red)x-color(blue)y = 7$
then
$color(white)("XXX")6color(red)a-color(blue)(11)=7$
$rarr$
$color(white)("XXX")6color(red)a=18$
$rarr$
$color(white)("XXX")color(red)a=3$
