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.
Answer:
n=8.4
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
