I apologize for the incorrect response. Let's go through the solution again.
The correct solution to the equation x + 2(x + 1) = 17 is as follows:
Line 1: x + 2(x + 1) = 17
Line 2: x + 2x + 2 = 17 (distributive property)
Line 3: 3x + 2 = 17 (combine like terms)
Now, to solve for x, we need to isolate x on one side of the equation:
Line 4: 3x = 17 - 2 (subtraction property of equality)
Line 5: 3x = 15
To find the value of x, we need to divide both sides of the equation by 3:
Line 6: x = 15/3
Simplifying Line 6 gives us:
Line 7: x = 5
So, the correct answer for the equation x + 2(x + 1) = 17 is x = 5.
