[3x-5y=20],[6x-10y=40]

In the following system of equations determine whether it has unique solution,no solution or infinitely many solutions.In case there is a unique solution,find it: 3x-5y=20,quad 6x-10y=40

Show graphically that following system of equations is in-consistent (i.e.has no solution): 3x-5y=20;quad 6x-10y=-40

In the following system of equations determine whether it has unique solution, no solution or infinitely many solutions. In case there is a unique solution, find it: 3x-5y=20 ,\ \ \ 6x-10 y=40

By comparing the ratios a_1/a_2,b_1/b_2,c_1/c_2 and without drawing graphs, find out whether the lines represented by the following pair of linear equations intersent at a point, are parallel or coincident. 3x-5y-20 = 0 6x-10y-40 = 0

Check whether the following equations are consistent or inconsistent. 3x-5y= 11, 6x-10y = 22

Show graphically that following system of equations is in-consistent (i.e. has no solution): 3x-5y=20 ;\ \ \ 6x-10 y=-40

Show that the system of equations 3x - 5y = 7, 6x - 10 y = 3 . has no solution.

5x-y=9; 6x-2y=10

6x-3y=-10,3x+5y-8=0

3x - y= 5, 6x - 2y = 10 .
