Final answer:
To solve the equation 3k - 7 = 11, add 7 to both sides and then divide by 3, which gives k = 6. The correct choice is option a.
Step-by-step explanation:
The correct answer is option a. To solve the equation 3k - 7 = 11, you first add 7 to both sides of the equation to isolate the term with the variable k on one side. This gives us:
3k - 7 + 7 = 11 + 7
3k = 18
Next, you divide both sides of the equation by 3 to solve for k:
3k / 3 = 18 / 3
k = 6
So, k equals 6, and the correct choice is option a: k = 6.
To solve the equation 3k - 7 = 11, you need to isolate the variable k.
Add 7 to both sides of the equation: 3k - 7 + 7 = 11 + 7.
Combine like terms: 3k = 18.
Divide both sides by 3: 3k/3 = 18/3.
Simplify: k = 6.
Therefore, the solution to the equation is k = 6.
