Solve 2x - 5 = 10?

x = 15
x = 7.5
x = -15
x = -7.5

The correct answer is: x = 15

First, we can add 5 to both sides of the equation to get 2x = 15. Then, we can divide both sides by 2 to isolate the variable x, resulting in x = 15/2 or x = 7.5. The other options are incorrect because when adding 5 to both sides, the incorrect answer for x would result in either a positive or negative 20, making the options B and D incorrect. Option C is incorrect because when dividing by 2, we would end up with a negative value for x rather than a positive 15. Therefore, option A is the only correct solution.
