Answer

no solution

Work Step by Step

Using the properties of equality, the given equation, $ 2|x|+25=23 ,$ is equivalent to \begin{array}{l}\require{cancel} 2|x|=23-25 \\\\ 2|x|=-2 \\\\ |x|=-\dfrac{2}{2} \\\\ |x|=-1 .\end{array} The left side of the equation above always gives a non negative value. This will never be equal to the negative value at the right. Hence, there is $\text{ no solution .}$
