x>4

Explanation:

Except in the case where you're multiplying or dividing both sides of an inequality by a negative number, you'd approach solving an inequality like you would any other algebraic equation.

25<2x+3x+5
25<5x+5 (combine like terms)
20<5x (subtract 5 from both sides)
4<x (divide both sides by 5 to isolate x)

x>4
