One simple way is to first move it to:

Then, graph both on graph paper and look for the solutions manually. - Oct 24th 2010, 11:30 AMArchie Meade
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. - Oct 24th 2010, 03:10 PMHallsofIvy
