[6x-5y=4],[2y+7=9x]

Solve the following pair of linear equations 3x-5y=4 and 2y+7=9x

Solve fir x and y: [5x-4y+8=0],[7x+6y-9=0]

Solve 6x-7y=16, 9x-5y=35 using (Cramer's rule).

Solve:- 3x-5y-4=0, 9x=2y+7

In each of the following systems of equations determine whether the system has a unique solution, no solution or infinitely many solutions. In case there is a unique solution, find it. (1) 2x+3y=7 , 6x+5y=11 (2) 6x+5y=11 , 9x+(15)/2y=21 (3) -3x+4y=5 , 9/2x-6y+(15)/2=0

Show that the system of equations " " 6x + 5y = 11, 9x + ( 15) /(2) y = 21 . has no solution

Solve by cross-multiplication method. (i) 8x-3y=12,5x=2y +7 (ii) 6x+ 7y -11 =0, 5x+ 2y =13 (iii) (2)/(x)+(3)/(y) =5, (3)/(x) -(1)/(y) +9=0

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

Solve the following pair of linear equatio: 3x-5y-4=0 9x=2y+7

Show that each of the following systems of linear equations is consistent and also find their solutions: 6x+4y=2 9x+6y=3 2x+3y=5 6x+9y=15 5x+3y+7z=4 3x+26 y+2z=9 7x+2y+10 z=5 x-y+z=3 2x+y-z=2 -x-2y+2z=1 x+y+z=6 x+2y+3z=14 x+4y+7z=30 2x+2y-2z=1 4x+4y-z=2 6x+6y+2z=3
