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

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;quad 6x-10y=-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

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

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

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

Solve: 5x+10y=35,10x+5y=40 .

The lines x-y-6=0, 4x-3y-20=0 and 6x+5y+8=0 are:
