Answer and step-by-step explanation:
[tex]Hello!~[/tex]
[tex]Let's~solve~your~equation![/tex]
Step 1: Simplify both sides of the equation:
[tex]k+4=16-(-9)[/tex]
[tex]k+4=16+9[/tex]
[tex]k+4=(16+9)[/tex] [tex](combine~like~terms)[/tex]
[tex]k+4=25[/tex]
Step 2: Subtract 4 from both sides:
[tex]k+4-4=25-4[/tex]
[tex]k=21[/tex]
The answer you should be getting is:
[tex]k=21[/tex]
