Question

How do you complete each ordered pair (_, 11) so that it is a solution to 6x - y = 7?

Answer 1

`(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`
