Question

Identify the solution of equation x+y=3​

Answer 1

Answer:

x=3-y iiiiiiiiiiiiiiiiiiiiiiiiiiiiii

Answer 2

$x + y = 3 ..(i)\\ x = 3 + y ..(ii) \\ \\ put \: (x = 3 + y)in \: equation \:( i)we \: get... \\ 3 + y + y = 3 \\ 3 + 2y = 3 \\ 2y = 3 - 3 \\ 2y = 0 \\ y = 0 \\ \\ now \: put \: y = 0 \: inequation \: (ii) \\ x = y + 3 \\ x = 0 +3 = 3$

• therefore ,x=3 and y=0
