Question 551505
"James is four years younger than Austin" ___ j = a - 4


"If three times James' age is increased by the square of Austin's age, the result is 28"
___ 3j + a^2 = 28


substituting ___ 3(a - 4) + a^2 = 28 ___ a^2 + 3a - 40 = 0 ___ (a + 8)(a - 5) = 0


solve for a, then substitute back to find j
