Asystem of equations is shown below. 2x-y=5 x+3y=0 which statement is true regarding this system ? a- to solve the system, multiply the second equation by 2 and then add the result to the first equations b- to solve the system, multiply the first equation by 3 and then add the result to the second equation. c- the system has no solution since the second equation is equal to 0. d- the system has infinitely many solutions since the second equation is equal to 0

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

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.
