Let the number be X

2X-3 = 2 + 3X

Then X = -5.

Five times the number = -25. Five less Than this = -25-5 = -30

A is the answer.

Dear Bunuel,

the answer choices still seem to be mixed up.

Could you rearrange them accordingly? :)

Best regards,
Chris

Let the number be x.

2x-3 = 3x+2
2x-3x=2+3
-x=5
x=-5.

5x-5 = -25+(-5) = -30. (Answer)
