Answer:
[tex]k=-\frac{15-R}{2}[/tex]
Step-by-step explanation:
We have been given an equation [tex]R-2k=15[/tex]. We are asked to solve our given equation for k.
We will use opposite operations to solve for k.
Subtract R on both sides:
[tex]R-R-2k=15-R[/tex]
[tex]-2k=15-R[/tex]
Divide both sides by -2.
[tex]\frac{-2k}{-2}=\frac{15-R}{-2}[/tex]
[tex]k=-\frac{15-R}{2}[/tex]
Therefore, the solution for our given equation is [tex]k=-\frac{15-R}{2}[/tex].
