Answer:
The value of w is -217.
Step-by-step explanation:
Consider the provided equation.
[tex]13+\frac{w}{7}=-18[/tex]
Subtract 13 from both sides.
[tex]13-13+\frac{w}{7}=-18-13[/tex]
[tex]\frac{w}{7}=-31[/tex]
Multiply both sides by 7.
[tex]\frac{w}{7}\times 7=-31\times 7[/tex]
[tex]w=-217[/tex]
Hence the value of w is -217.
