Question 1059992
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
