a)

N + 7  = 18          subtract 7 from both sides

N  =  11

 

b)

N  -  6  = 24        add 6 to both sides

N  =  30

 

c)

5N  =  45            divide both sides by 5

N  = 9

 

d)

N/6  =  7          multiply both sides by 6

N  =   42

 

e)

4N +  3   =  19        subtract 3 from both sides

4N  =  16                 divide both sides by 4

N  = 4
