The Total solution for NCERT class 6-12
Show that each one of the following systems of linear equations isconsistent:
(i) 2x + 5y = 7
6x + 15y = 13
(ii) 2x + 3y = 5
6x + 9y = 10
(iii) 4x – 2y = 3
6x – 3y = 5
(iv) 4x – 5y – 2z = 2
5x – 4y + 2z = -2
2x + 2y + 8z = -1
(v) 3x – y – 2z = 2
2y – z = -1
3x – 5y = 3
(vi) x + y – 2z = 5
x – 2y + z = -2
-2x + y + z = 4
