Answer:
w = -19
Explanation:
To solve this equation, subtract ten from both sides. This will isolate the variable (w) and allow us to find its value.
[tex]10 + w = -9\\(10 - 10) + w = (-9 - 10)\\w = (-9 - 10)\\w = -19[/tex]
If you would like to double check that the variable (w) does in fact equal negative nineteen, substitute the value of the variable in the equation and solve.
[tex]10 + w = -9\\10 + -19 = -9\\-19 = -19 [true][/tex]
Therefore, the value of w in the given equation is -19.
