Question

whats the solution of 5x-y=9 and 6x+y=13

Answer 1

Answer:

$x = 2 \\ y = 1$

Step-by-step explanation:

$5x - y = 9..equation(1) \\ \\ 6x + y = 13...equation(2) \\ \\ = > take \: a \: sum \: of \: equation \: (1) \: and \: equation(2) \\ \\ 5x - y = 9 \\ \\ 6x + y = 13 \\ ..................... \\ 11x + 0 = 22 \\ \\ 11x = 22 \\ \\ x = \frac{22}{11 } \\ \\ x = 2 \: ....ans \\ \\ = > put \: value \: of \: x \: in \: equation \: (1) \: or \: equation \: (2) \\ \\ 5x - y = 9 \\ \\ 5(2) - y = 9 \\ \\ y = 10 - 9 \\ \\ y = 1....ans$

Answer 2

Answer:x=2,y=1

Step-by-step explanation:when you will add both the equation y will be cancelled and you will get 11x=22 therefore x=2 and when you put this value in any of the equation you will get y=1
