Answer:
Explanation:
continuing from the 3rd line....
10x - 1 = 10x + 8 (subtract 10x from both sides)
10x - 10x - 1 = 10x -10x + 8
-1 = + 8 (this last line is not part of the solution but i'm showing it here so you can see what is going on, obviously -1 cannot be 8)
Since -1 ≠ 8, the equation has no (i.e zero) solutions
