Question

Solve the equation for k R-2k=15

Answer 1

R - 2k = 15......subtract R from both sides
-2k = 15 - R...divide both sides by -2
k = -15/2 + 1/2R

Answer 2

`k=-(15-R)/(2)`

Explanation:

We have been given an equation
`R-2k=15`. We are asked to solve our given equation for k.

We will use opposite operations to solve for k.

Subtract R on both sides:

`R-R-2k=15-R`

`-2k=15-R`

Divide both sides by -2.

`(-2k)/(-2)=(15-R)/(-2)`

`k=-(15-R)/(2)`

Therefore, the solution for our given equation is
`k=-(15-R)/(2)`.
