9514 1404 393

Answer:

x > -5

Explanation:

(2/5)(x -1) < (3/5)(x +1) . . . . . given

2(x -1) < 3(x +1) . . . . . . . . . . .multiply by 5

2x -2 < 3x +3 . . . . . . . . . . . eliminate parentheses

-5 < x . . . . . . . . . . . . . . . . . . add -2x-3 to both sides

This matches the second answer choice: x > -5.
