Question 284176
what two numbers added together that equals 70 but when multiplied it equals 600
---------------------------------
Equation:
x + y = 70
xy = 600
------------------
y = 70-x
---
Substitute and solve for "x":
x(70-x) = 600
70x -x^2 = 600
x^2-70x+600 = 0
---
Factor:
(x-10)(x-60) = 0
---
If x = 10, y = 60
If x = 60, y = 10
