Question

(5,3) is solution of 2x+3y+k=0.if (m,5) is another solution of this equation then m=​

Answer 1

Step-by-step explanation:

$(5 \:, 3) \: is \: solution \: of \: 2x + 3y + k = 0. \\ Then \:, 10 + 9 + k = 0 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: 19 + k = 0 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: k = - 19 \\ \\ The \: equation \: is \: 2x + 3y - 19 = 0 \\ (m \:, 5)is \: the \: solution \\ Then \:, 2m + 15 - 19 = 0 \\ \: \: \: \: \: \: \: \: \: \: \: \: 2m - 4 = 0 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: m = 2 \\ \\ Hope \: it \: will \: help \: you.$
