To solve the equation 3x + 2 = x + 8, you need to isolate the variable x.
Subtract x from both sides of the equation:
3x - x + 2 = x - x + 8
2x + 2 = 8
Subtract 2 from both sides of the equation:
2x + 2 - 2 = 8 - 2
2x = 6
Divide both sides of the equation by 2:
2x/2 = 6/2
x = 3
The solution to the equation 3x + 2 = x + 8 is x = 3.
Therefore, the answer is C. 3.
