Final answer:
To find the unknown number ('x'), an equation is set up as -5x + 20 = -95. After subtracting 20 from both sides and then dividing by -5, we find that x equals 23.
Step-by-step explanation:
The student asks who they are if, when multiplied by -5 and then 20 is added, the result is -95. To solve this, we will set up an equation where the unknown number is represented by 'x'.
Our equation based on the question is: -5x + 20 = -95
To find 'x', we will first subtract 20 from both sides:
- -5x + 20 - 20 = -95 - 20
- -5x = -115
Next, we will divide both sides by -5 to isolate 'x':
- -5x / -5 = -115 / -5
- x = 23
So, the student's identity in this mathematical scenario is 23.
