+219 Let $x$ and $y$ be nonnegative real numbers. If $x + y = 25$, then find the minimum value of $6x + 3y.$
+1926 Alright. Let's first isolate y. We have \(y=25-x\)
Subbing this into the second equation, we get \(3x + 75\)
Well, the minimum value where x is not negative is when x is 0.
When x is 0, we get \(3(0)+75=75\)
So 75 is our answer!
Thanks! :)
