Let's translate the two expressions into formulae:

11 less than three times a number:
3x-11

75 less than the product of -1 and the number
-x-75

Those two are the same, so we have


3x-11=-x-75

Add
x to both sides:


4x-11=-75

Add 11 to both sides:


4x=-64

Divide both sides by 4 to get the final answer.
