How many solutions does the following equation have 10x-1 = 10x + 4 A no solutions B infinitely many solutions C two solutions D one solution

The equation is of the form "10x-1 = 10x + 4". By subtracting 10x from both sides, we get "-1 = 4", which is not true. Thus, there are no solutions. Therefore, the answer is A) no solutions.
