The solution to the equation 4x - 9 = 11 is x = 5.
We will use the appropriate algebraic operations to isolate the variable x in order to solve the equation 4x - 9 = 11 for x.
Here is the detailed answer:
Let's start with the formula: 4x – 9 = 11.
To get rid of the constant term on the left side, add 9 to both sides of the equation:
4x - 9 + 9 = 11 + 9.
When we simplify, we obtain 4x = 20.
To separate x, divide both sides of the equation by 4:
(4x)/4 = 20/4.
To further simplify, we have x = 5.
As a result, x = 5 is the answer to the equation 4x - 9 = 11.

39F=? C rounded to the nearest tenth of a degree
To convert temperatures in degrees Fahrenheit to Celsius, subtract 32 and multiply by .5556 (or 5/9).
5F= -15C
39F= 3.9C
Here's how you can convert Fahrenheit to Celsius:
1. First, we need to subtract 32 from the Fahrenheit temperature.
For 5F, we would do 5 - 32 to get -27.
For 39F, we would do 39 - 32 to get 7.
2. The next step in our conversion process is to multiply the result by 5/9.
For -27, we would do (-27 * 5/9) to get -15.
For 7, we would do (7 * 5/9) to get approximately 3.888888888889, but we want our result rounded to the nearest tenth of a degree. Thus, we round this value to 3.9.
So, to convert 5F to Celsius you get -15C and to convert 39F to Celsius you get 3.9C.
