Question

Solve the equation for k R-2k=15

Answer 1

Answer:

$k=-\frac{15-R}{2}$

Step-by-step 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.

$\frac{-2k}{-2}=\frac{15-R}{-2}$

$k=-\frac{15-R}{2}$

Therefore, the solution for our given equation is $k=-\frac{15-R}{2}$.

Answer 2

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