Final answer:
To solve the equation 2c + 4 = 10, subtract 4 from both sides and then divide both sides by 2 to get the solution c = 3. Neither 2 nor 6 is a solution to the equation.
Step-by-step explanation:
The given equation is 2c + 4 = 10, where c represents the number of candy bars Kevin bought. To solve this equation, we need to isolate the variable c.
Step 1: Subtract 4 from both sides of the equation to get 2c = 6.
Step 2: Divide both sides of the equation by 2 to get c = 3.
Therefore, the solution to the equation is c = 3.
Since neither 2 nor 6 satisfy the equation, the students are correct in saying that neither 2 nor 6 is a solution to the equation.
