Answer: The corrected solution to the equation 5x + 8 = x is x = -2.

Explanation:

In the original equation, you want to get all the terms involving x on one side and constants on the other side. To do this, you should subtract x from both sides, not add x.The incorrect step in the original equation: 5x + 8 = x

Correcting this step:

Subtract x from both sides:

5x - x + 8 = 0

Now, simplify the equation:

4x + 8 = 0

Next, isolate x by subtracting 8 from both sides:

4x + 8 - 8 = 0 - 8

4x = -8

Finally, solve for x by dividing both sides by 4:

(4x) / 4 = (-8) / 4

x = -2
