Isolate the x. Subtract 20x from both sides, and add 15 to both sides

-5x (-20x) - 15 (+15) > 10 (+15) + 20x (-20x)

-5x - 20x > 10 + 15

Simplify. Combine like terms

-25x > 25

Isolate the x. Divide -25 from both sides. Note that when you are dividing by a negative number, flip the sign.

(-25x)/-25 > (25)/-25

x > 25/-25

x < -1

x < -1 is your answer

hope this helps
