if 2k - 4 = 8, then k is what
2k - 4 = 8
2k = 8 + 4
2k = 12
k = 12/2
k = 6
To find the value of k in the equation 2k - 4 = 8, we can solve for k by using basic algebraic operations. I will walk you through the steps:
1. Start with the equation: 2k - 4 = 8.
2. Add 4 to both sides of the equation to isolate the term containing k: 2k - 4 + 4 = 8 + 4.
Simplifying, we get: 2k = 12.
3. Now, we want to isolate k, so we need to divide both sides of the equation by 2: 2k/2 = 12/2.
The result is: k = 6.
Therefore, in the equation 2k - 4 = 8, the value of k is 6.
