For what value of k, the pair of equations 2x+3y+5=0 and kx+4y=10 has

1.	For what value of k, the pair of equations 2x+3y+5=0 and kx+4y=10 has a unique solutions
Answer» 64 The equation will have unique solution for all number except 8/3 » 2x + 3y + 5 = 0» kx + 4y = 10➡ kx + 4y - 10 = 0we have to find the value of\xa0k\xa0such that the pair of equations have unique solution.we know that, when pair of equations have unique solution,a1/a2 ≠ b1/b2➡ 2/k ≠ 3/5just put any value of\xa0k\xa0so that it doesn\'t get equal to 3/5.you can put 1, 2 etc.for example, k is 2, then a1/a2 = 2/2 = 1LHS ≠ RHS
