Answer: The required value of x is -9.5.
Step-by-step explanation: We are given to find the value of x from the following sentence after translating it into an equation :
"twice x, plus 5 is the same as -14".
According to the given information, the equation can be written and solved as follows :
[tex]2x+5=-14\\\\\Rightarrow 2x=-14-5\\\\\Rightarrow 2x=-19\\\\\Rightarrow x=-\dfrac{19}{2}\\\\\Rightarrow x=-9.5.[/tex]
Thus, the required value of x is -9.5.
