It is always a good practice to define the variables, in this case:

son's age = x

Jerry's age = 6+3x

Together

x + (6+3x) = 46

so x + 6+3x =46

4x + 6-6 = 46 - 6

4x/4 = 40/4

x = 10 ???? it should be 36 what am I missing?

son's age = x

Jerry's age = 6+3x

"...how old is jerry. "

4x divided by 4 = x

40 divided by 4 =10

if x = 10

then

6+3x = 6+30
