Answer:

k = 3

Step-by-step explanation:

4 - 7k = 1 - 6k

4 - 1 = - 6k + 7k

3 = k

k = 3

p.s. I changed 3 = k to k = 3 because most math teachers prefer for the answer to be in that order.

Answer:

3 = k

Step-by-step explanation:

Step 1: Write equation

4 - 7k = 1 - 6k

Step 2: Solve for <em>k</em>

<u>Add 7k on both sides:</u> 4 = 1 + k

<u>Subtract 1 on both sides:</u> 3 = k
