Solve −np − 90 < 30 for n. Show your work.

Also solve 5m − 3h = 45 for h. Show your work.

-np - 90 < 30      subtract 30 from both sides, add np to both sides

 

-120  < np         divide both sides by  p

 

-120 / p <   n

 

 

 

 

 

9m - 3h  = 45     add 3h to both sides, subtract 45 from both sides

 

9m - 45  = 3h      divide every term by 3

 

3m - 15  = h

 

 

Corrected answer....thanks to guest for spotting my error   !!!
