Question

Find a linear equation with two variables that, together with the

equation 10x + 5y = 1, would comprise a system
with one solution

Answer 1

y = x

Explanation:

Any equation that describes a different line will be part of a system with exactly one solution. There are an infinite number of possible equations.

Perhaps one of the simplest is ...

y = x

_____

Together with the given equation, this has the solution ...

x = y = 1/15
