Solve the following systems of linear equations. If it is inconsistent or dependent say so. If dependent, state the solution set. To get full credit you must show your work and check your answers. If your answers do not check but you cannot find your mistake, you can get some points back by stating that you realize the failure to check means there is an error somewhere 3x- y +22 = 15 4x-3y-z= 27 5x + 6y-22 = 15 6x-3y-22 = 45 12x + 6y +4z=-90 18x-9y-62= 135 8 7x - y- z 72 5x 5y 3z- 34 6x + 5y-22-29 ã§ã¨ã§- + 3 2 3 5x-2y +3ã«47 10 10x-3y-z= 38 7x-4y+32= 49 -4x + 5y-72= -60 4 5x-3y-4z = -89 -7x + 12y +62= 173 5x- y + 4z = 61 8x-5y +62= 107 x + 7y = -10 12 10x 3y - z- 38 7x-4y+32= 49 6 13 8x-ÐÑ- 22= 41 5x-3y-22: 26 -6x + 3y-z=-43
