So I would begin by minusing 5 from both sides and that will give you 3x - 5 ≤ 4x. Then we want to gather our x's onto one side, so I would '-3x' from both sides which leaves you with - 5 ≤ 4x - 3 x, s...

Firstly we must appreciate that if there is an intersection between l and m, this means that there exists a point that occurs on both lines. Therefore if there is an inte...
