A positive integer is 47 more than 9 times another. Their product is 1860. Find the two integers.

X = 47 + 9y

xy = 1860

y (47 + 9y) = 1860

47y + 9y² = 1860

9y² + 47y - 1860 = 0

> using a quadratic equation solver on a calculator but you can also use the quadratic equation = [-b + / - √ (b²-4ac) ] / (2a)

> only integer solution is x = 12

12y = 1860

y = 155

integers are 12 and 155
