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)

Let x be the number

3 less than twice a certain number is equal to 2 more than 3 times the number
We can write: 2x - 3 = 3x + 2
So: -3 = x + 2
Solve: -5 = x

5 less than 5 times the number is
5 times the number = 5(-5) = -25
So, 5 less than 5 times the number = -25 - 5 = -30

Answer: A

Cheers,
Brent

We can create the equation:

2n - 3 = 2 + 3n

-5 = n

Thus, 5 less than 5 times the number is 5(-5) - 5 = -25 - 5 = -30.

Answer: A
