You command us?!

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

3. One simple way is to first move it to:

$|3x + 4| > 2 + |2x + 3|$

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

$3x+4$ and $2x+3$ are linear expressions (thanks HallsofIvy!)

If you solve the equation $(3x+4)=(2x+3)\Rightarrow\ x=-1$

They are equations of lines if we write y = expression, with different slopes, hence $(3x+4)>(2x+3)$ to the right of $x=-1$

and $(2x+3)>(3x+4)$ to the left of $x=-1$

If $(3x+4)>(2x+3)$ you need to solve for $(3x+4)-(2x+3)>2$

If $(2x+3)>(3x+4)$ you need to solve for $(2x+3)-(3x+4)>2$

You need both solutions.

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