Respuesta:

x + 24 = 56 \\ x = 56 - 24 \\ x = 32 \\

x + 2 = 6 \\ x = 6 - 2 \\ x = 4

x + 5 = 103 \\ x = 103 - 5 \\ x = 98

x  + 36 = 256 \\ x = 256 - 36 \\ x = 220

x + 23 = 698 \\ x = 698 - 23 \\ x = 675

x - 12 = 546 \\ x = 546 + 12 \\ x = 558

x - 96 = 359 \\ x = 359 + 96 \\ x = 455

x - 593 = 193 \\ x = 193 + 593 \\ x = 786

x - 12.5 =  - 10.8 \\ x =  - 10.8 + 12.5 \\ x = 1.7

x - 53.89 =  - 60 \\ x =  - 60 + 53.89 \\ x =  - 6.11

3 + x = 13 \\ x = 13 - 3 \\ x = 10

15 + x = 69.5 \\ x = 69.5 - 15 \\ x = 54.5

362 - x = 46 \\  - x = 46 - 362 \\  - x =  - 316 \\ x = 316

1568 - x = 568 \\  - x = 568 - 1568 \\  - x =  - 1000 \\ x = 1000

23.5 - x = 50 \\  - x = 50 - 23.5 \\  - x = 26.5 \\ x =  26.5

Para verificar que estén correctas solo tienes que sustituir la x por el valor correspondiente.
