Question

I need help with this I was absent in school and the teacher won’t help me

Answer 1

Explanation:

Given the equation

-45n + 45 = 90

Step 1: Isolate n

We can isolate n by subtracting 45 from both sides

-45n + 45 - 45 = 90 - 45

-45n + 0 = 45

-45n = 45

Divide through by -45

-45n/-45 = 45/-45

n = -1

Hence, the value of n is -1
