j = Josh's age
j - 2 = Clayton's age {Clayton is 2 years younger than Josh}
j + j - 2 = 20 {sum of their ages is 20}
2j - 2 = 20 {combined like terms}
2j = 22 {added 2 to each side}
j = 11 {divided each side by 2}
j - 2 = 9 {substituted 11, in for j, into j - 2}
Josh is 11
Clayton is 9

-----
c = j-2
c + j = 20
----------
Substitute for "c" and solve for "j"::
j-2 + j = 20
2j = 22
josh = 11 yrs
------
clayton = j-2 = 9 yrs
