What is the value of k in the equation 8 + 2k = 4k + 4

Step 1. Subtract 2k from both sides
8 = 4k + 4 - 2k
Step 2. Simplify 4k + 4 - 2k to 2k + 4
8 = 2k + 4
Step 3. Subtract 4 from both sides
8 - 4 = 2k
Step 4. Simplify 8 - 4 to 4
4 = 2k
Step 5. Divide both sides by 2
4/2 = k
Step 6. Simplify 4/2 to 2
2 = k
Step 7. Switch sides
Your answer is k = 2

8+2k=4k+4
8-4=4k-2k                   I placed the like terms on each side.
4=2k                           Simplify
4/2=k                          Leave the variable a side
2 = k
