Part a: solve −np − 70 < 40 for n. show your work. (4 points) part b: solve 4w − 7k = 28 for k. show your work.

Hey!

For part A, let's write the problem,

Add to both sides...


We are going to reverse the inequality, to do this we are going to multiply both sides by .


Divide both sides by .

Our answer would be,


Let's go with Part B. Let's write the problem,

Subtract from both sides,


Divide both sides by .

If we simplified it, we would be left with,
