`3x+2y=5` `2x-3y=7`

3x-4y=-7,5x-2y=0

{:(3x + 2y = 4),(2x - 3y = 7):}

{:(3x + 2y = 4),(2x - 3y = 7):}

Check whether (5,-1) is a solution of the simultaneous equations x-2y=7 and 2x+3y=7.

Solve the following system of equations by matrix method : 5x+7y+2=0 4x+6y+3=0 5x+2y=3 3x+2y=5 3x+4y-5=0 x-y+3=0 3x+y=19 3x-y=23 3x+7y=4 x+2y=-1 3x+y=7 5x+3y=12

5x+2y=4 7x+3y=5

if (3x-2y):(5x-7y)=5:3 then, find x:y.

solve for x and y 2x-3y+7=0 3x+4y-5=0
