jerry is 6 more than 3 times as old as his son.together they are 46 yrs old. how old is jerry. ans 36
I set up problem 6+3x=46 to start?

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 
got it, thanks
