Answer: n = 8.4
Step-by-step explanation:
40 - 5n = - 2
First, subtract 40 from each side of the equation
-5n = - 42
Then, divide each side by - 5
n = 8.4
The - 5 and - 42 cancel each other out when dividing, so n = 8.4 is positive.

n=8.4
Step-by-step explanation:
To solve, we need to isolate the variable, n
40 - 5n = -2
Subtract 40 from both sides
40-40-5n = - 2 - 40
-5n = - 42
Divide both sides by - 5
-5n/-5=-42/-5
n=42/5
n=8.4
