Rylee Mcmahon · Answer 1

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.

Braylen Lin · Answer 2

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
