PLEASE HELP Give an example of an equation that has no solution and show why:

2x-3=2x-4

Step-by-step explanation:

2x-3=2x-4

-3=-4

Not true. Thus, no solution.

say the equation was 2x - 5 = 2x -3

well the first thing I could do is subtract the 2x from both sides, but 2x is on both sides so there would be no x-value meaning there is no solution

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
