Question

How do you solve the system of equations `y= 2x - 7` and `y = 2x - \frac { 8} { 9}`?

Answer 1

There are no possible solutions to this system of equations.
(The equations represent parallel lines with no intersection point).

Explanation:

If
`color(white)("XXX")y=2x-7`
and
`color(white)("XXX")y=2x-8/9`
then
`color(white)("XXX")2x-7=2x-8/9`
and
`color(white)("XXX")-7=-8/9`

...but obviously this is not true.
