Part a: solve −np − 70 < 40 for n. show your work. (4 points) part b: solve 4w − 7k = 28 for k. show your work. (6 points

For part A, lets 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 



lets go with part b, lets write the problem



subtract  from both sides





divide both sides by 



I few simplified it, we would be left with,



I hope this helped!!
