Question

13. If x = -2, y = -1 is a solution of mx +2y = 15. Find the value of 'm'.​

Answer 1

Answer:

$since \: x = -2, \: y = -1 \: is \: a \: solution \: of \: mx +2y = 15. \\ therefore \: ( - 2)m + 2( - 1) = 15 \\ - 2m - 2 = 15 \\ - 2m = 17 \\ m = - \frac{17}{2}$

Answer 2

Answer:

this is correct.................
