Answer:
x = 5/2
Step-by-step explanation:
Isolate x by adding 2x to both sides, obtaining: 5 - 2x + 2x = 2x. Then 5 = 2x, and dividing both sides by 2 results in x = 5/2.
6 + 28 + 4x +28
34 +28 + 4x
62 + 4x?
Not quite sure if that was what you were looking for
Given

To obtain the minimum value of y, we first take the derivative of y
The derivative of y is:

Equating

gives the minimum value we require.
Doing that, we have:

So that

Therefore, the minimum value is x = 3
We can know from the pic
2x+38=90
so, x=26
