Square both sides. (5-2x) - (2-x) = 1^2. 5 - 2x - 2 + x = 1. Simplify to get 3 - x = 1. X=2
Answer: x < 2
<u>Step-by-step explanation:</u>
2x + 1 < 5
Subtract 1 from both sides:
2x < 4
Divide both sides by 2:
x < 2 <em>(x is less than 2)</em>

The following formula is used to find the answer.
D = 50 mg (0.6^n)
D is the dosage
n is at any hour
Using this formula and solving the equation for it, the answer is 18.
8 so it would be 2/8 plus 3/8
