Which of the following equations have no solutions? Choose all answers that apply:
5x + 5 = -4.0-5
4x + 5 = -435
- 4x + 5 = - 48 - 4
- 4x + 5 = – 4x – 5

Answer D

Step-by-step explanation:

First equation

5x + 5 = (-4) - 5

5x + 5 = -9

5x = -14

x = -2.8

Solvable

Second equation

4x + 5 = -435

4x = -440

x = -110

Solvable

Third equation

-4x + 5 = (-48) - 4

-4x + 5 = -52

-4x = -57

4x = 57

x = 14.25

Solvable

Fourth equation

-4x + 5 = -4x - 5

5 = -5
