" (i) "7x-3y" and "4x-5y

Solve: 2x-3y=3 and 4x-5y=7

Multiply (7x-3y) by (4x-5y) by column method.

Multiply (7x-3y) by (4x-5y) by column method.

Given the four lines with equations x+2y-3=0, 3x+4y-7=0, 2x+3y-4=0 and 4x+5y-6=0 , then:

The value of k for which the lines 7x -8y +5=0, 3x-4 y+5 =0 and 4x+5y+k =0 are concurrent is given by

The value of k for which the lines 7x -8y +5=0, 3x-4 y+5 =0 and 4x+5y+k =0 are concurrent is given by

Examine whether the following system of linear equations is consistent or not. If consistent solve the system : 7x+3y=0, 4x-5y=0
