Answer:


x<2.5 and
x > 2.5 are the solutions

Explanation:

Given


-4x + 5 > -5


-25 > -5(x + 2.5)

Required

Determine if their solution is x < 2.5 or x > 2.5


-4x + 5 > -5

Collect like terms


-4x>-5-5


-4x>-10

Divide by -4


x<(-10)/(-4)


x<2.5


-25 > -5(x + 2.5)

Open bracket


-25 > -5x - 12.5

Collect like terms


5x > 25- 12.5


5x > 12.5

Divide by 5


x > (12.5)/(5)


x > 2.5
