Question

find the solution..x+y=3 and 7x+6y=2​

Answer 1

Answer:

$x + y = 3...(1) \\ 7x + 6y = 2...(2 )\\ multiply \: equation \: (1) by \: 6 \\ 6x + 6y = 18...(3) \\ now \\ subtract \: equation \: (2)from(3) \: we \: get \: \\ - x = 16 \\ x = - 16 \\ put \: x = - 16in \: eq \:(1) - 16 + y = 3 \\ y = 3 + 16 \\ y = 19$

Answer 2

this is the solution of X + Y is equal to 3 and 7 x + 6 Y is equal to 2
