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
