The left side 4+5m is the same as 5m+4

Simplifying the right hand side has 4m+1+m turn into 5m+1

The original equation is equivalent to 5m+4 = 5m+1

If we subtract 5m from both sides, the 5m terms cancel leaving us with 4 = 1, but that's not a true statement.

Regardless of whatever value you pick for m, the original equation will not be true.

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.
