x+2y=6 સમીકરણના ચાર જુદા જુદા ઉકેલો શોધો. | 9 | બે ચલોમાં રેખીય સમીકરણો | ...

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

(x)/(2) - ( y )/(9) = 6, ( x) /( 7) + ( y ) /(3) = 5 .

6x+4y=5 9x+6y=8

The line 3x + 2y + 7 = 0 and 6x + 4y + 9 = 0 are "___________" to each other .

solve: (2) / (2x + y) - (1) / (x-2y) + (5) / (9) = 0 and (9) / (2x + y) - (6) / (x-2y ) + 4 = 0

Equation of a common chord of the circles x ^(2) + y ^(2) + 6x -10 y + 9=0 and x ^(2) + y ^(2) - 10 x + 6y + 25=0 is

The circle x ^(2) + y ^(2) =9 is contained in the circle x ^(2) + y ^(2) - 6x - 8y + 25=c^(2) If

2x+3y=5 6x+9y=10
