Let $x$ and $y$ be nonnegative real numbers. If $x + y = 25$, then find the minimum value of $6x + 3y.$
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! :)
