For two linear equations a_(1)x + b_(1)y + c_(1)= 0 and a_(2) x+ b_(2)y+ c_(2)= 0 , then condition (a_(1))/(a_(2)) = (b_(1))/(b_(2))= (c_(1))/(c_(2)) is for

If the equations 4x + 6y = 15 and 8x +ky = 30 have infinite solutions, then find the value of k . The following are the steps involved in solving the above problem. Arrange them in sequential order. (A) (4)/(8) = (6)/(k) = (-15)/(-30) rArr (6)/(k) = (1)/(2) (B) We know that, if a_1x+ b_1y + c_1 =0 and a_2 x + b_2 y + c_2=0 have infinite solutions, then (a_1)/(a_2) = (b_1)/(b_2) = (c_1)/(c_2) . (C) Given that, 4x + 6y - 15 =0 and 8x + ky - 30 =0 have infinite solutions. (D) therefore k = 12 .

Assertion (A) :Pair of linear equations 9x+3y+12=0 and 18x+6y+24=0 have infinitely many solutions Reason (R ) : Pair of linear equations a_(1)x+b_(1)y+c_(1)=0 and a_(2)x+b_(2)y+c_(2)=0 have infinitely many solutions if (a_(1))/(a_(2))=(b_(1))/(b_(2))=(c_(1))/(c_(2))

If the system of equations a_(1)x+b_(1)y+c_(1),a_(2)x+b_(2)y+c_(2)=0 is inconsistent,(a_(1))/(a_(2))=(b_(1))/(b_(2))!=(c_(1))/(c_(2))

Statement-1: If the equations ax^2 + bx + c = 0 (a, b, c in R and a != 0) and 2x^2 + 7x+10=0 have a common root, then (2a+c)/b =2. Statement-2: If both roots of a_1 x^2 + b_1 x+c_1 = 0 and a_2 x^2 + b_2x + c_2 = 0 are same, then a_1/a_2=b_1/b_2=c_1/c_2. Given a_1,b_1,c_1,a_2,b_2,c_2 in R and a_1 a_2 != 0.
