Question 1107217
x = Jack's age
x + 8 = Ana's age   {Ana is 8 years more than Jack}


x + x + 8 = 70   {sum of their ages is 70}
2x + 8 = 70   {combined like terms}
2x = 62   {subtracted 8 from each side}
x = 31   {divided each side by 2}
x + 8 = 39   {substituted 31, in for x, into x + 8}


Jack is 31
Ana is 39
