Answer:
The value of k is 0.
Step by step explanation:
The given equation is
[tex]-k+78=98-20[/tex]
We need to find the value of k.
Simplify the right side of the equation.
[tex]-k+78=78[/tex]
Subtract 78 from both sides.
[tex]-k+78-78=78-78[/tex]
[tex]-k=0[/tex]
Divide both sides by -1.
[tex]k=0[/tex]
Therefore, the value of k is 0.
