To solve the equation 8-2x=5(x-2), we need to follow these steps:
1. Distribute the 5 on the right side of the equation:
8-2x = 5x - 10
2. Combine like\) to both sides:
8 = ) 3. Add 10 to both sides to \(18 = 7x
So,. 18=7x
B. 8=7x-10
C. 8-2x=5x-10
The step that is not part of solving the problem is:
D. 8-2x=5x-2
This step is incorrect because it does not follow from the previous steps and does not help in solving the equation.
