Let x be "a number".


Then from the condition, you have this equation


    3x - 11 = (-1)*x - 75      (1)


Simplify and solve for x


    3x - 11 = - x - 75

    3x + x  = 11 - 75

      4x    = - 64

       x    = -64/4 = -16.


ANSWER.  The number is -16.





Solved.

The starting equation was written incorrectly in the post by  @MathLover1.





BOTH  sides of her starting equation are  INCORRECT  TRANSLATION 



of the wording condition  (of  English)  to  Math.





Thanks to tutor @MathTherapy who noticed this error.







And  ONLY  BECAUSE  she made this error  TWICE  in  BOTH  SIDES  of the equation, 

her solution was eventually correct.







For your safety,  I recommend you to ignore the post by  @MathLover1,  since it contains 



VERY  DANGEROUS  errors,  wtat may harm your understanding.







Use the correct solution from my post.
