How to solve it (sorry SR): an inequality works just like an equality, except it changes direction if you multiply by a negative number (and if you multiply by a variable, there are two cases, in case the variable is positive and in case it is negative).

In this case, solve for x in the normal way: subtract 5 from both sides, then divide both sides by 2 (note 2 is positive so the inequality sign is still >), this isolates x on the LHS. You work it out!

Nobody is going to answer questions like these for you. It is apparent that you don’t want to learn. Go and study your inequalities again, and you will be able to solve this.
