You command us?!

Hmmm... show your trying effort for solving the problem...

One simple way is to first move it to:



Then, graph both on graph paper and look for the solutions manually.

and are linear expressions (thanks HallsofIvy!)

If you solve the equation

They are equations of lines if we write y = expression, with different slopes, hence to the right of

and to the left of

If you need to solve for

If you need to solve for

You need both solutions.

Well, no, they are not. They are linear expressions!
