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 + 66 = 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
