Answer:


\boxed {x > -(10)/(7)}

Explanation:

Solve the given inequality:


2(x - 1) - 4(x + 2) < 5x

-Use Distributive Property:


2(x - 1) - 4(x + 2) < 5x


2x - 2 - 4x - 8 < 5x

-Combine like terms:


2x - 2 - 4x - 8 < 5x


-2x - 10 < 5x

-Subtract both sides by
5x:


-2x - 10 - 5x < 5x - 5x


-7x - 10 < 0

-Add both sides by
10:


-7x - 10 + 10 < + 10


-7x < 10

-When you are dividing a integer by a negative integer, the inequality sign would change. So, divide both sides by
-7:


(-7x)/(-7) < (10)/(-7)


\boxed {x > -(10)/(7)} (final answer)
