Remember that standard form is the following:

Thus, let's first work on getting
and
to the same side of the equation. Let's subtract
from both sides of the equation and see what that gets us:

Rearranging the terms on the left side gets us:

However, in standard form,
must be positive, so let's multiply both sides of the equation by -1 to cancel out the first negative sign:

Our answer is 6x - y = 5.
