अनुपातों `(a_(1))/(a_(2)),(b_(1))/(b_(2))` and `(c_(1))/(c_(2))` की तुलना कर ज्ञात कीजिए कि निम्न समीकरण युग्म द्वारा निरूपित रेखाएं एक बिंदु पर प्रतिच्छेद करती है, समांतर है अथवा संपाती है:
(i) `{: (4x-4y+8=0),(7x+8y-9=0):}`
(ii) `{:(9x+3y+12=0),(18x+6y+24=0):}`
(iii) `{: (6x-3y+10=0),(2x-y+9=0):}`

Solve 9x+3y+12=0 18x+6y+24=0

Find value of x and y: (5x-4y+8=0),(7x+6y-9=0)

Find value of x and y: (5x-4y+8=0),(7x+6y-9=0)

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

On comparing the ratios (a_(1))/(a_(2)),(b_(1))/(b_(2)) and (c_(1))/(c_(2)), and without drawing them,find out whether the lines representing the following pairs of the equations intersect at a point,are parallel or coincide: 8=0;quad 7x+6y-9=0 (ii) 9x+3y+12=0;quad 18x+6y+24=0 (iii) 6x-3y+10=0;quad 2x-y+9=0

On comparing the ratios (a_1)/(a_2),(b_1)/(b_2) and (c_1)/(c_2) , and without drawing them, find out whether the lines representing the following pairs of linear equations intersect at a point, are parallel or coincide: (i) 5x-4y+8=0;\ \ \ \ 7x+6y-9=0 (ii) 9x+3y+12=0;\ \ \ 18 x+6y+24=0 (iii) 6x-3y+10=0;\ \ \ 2x-y+9=0

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
