11k + 9 = 42

Short answer

The answer is k = 3

Step-by-step solution

Step-1 – Given

The given equation is:$11k+9=42$

Step-2 – To determine

We have to solve the equation for k.

Step-3 – Calculation

The given equation is:

$\begin{array}{l}11k+9=42\\ 11k=42-9\left[\text{movetheliketerms}\right]\\ 11k=33\left[\text{subtract}\right]\\ k=\frac{33}{11}\left[\text{crossmultiply}\right]\\ k=3\left[\text{divide}\right]\end{array}$

So, the answer is $k=3$
