Question

solve the following pair of linear equation x+4y=8 & 2x+8y=16​

Answer 1

$we \: have \\ \: \: \: x + 4y = 8 \\ \: \: \: x = 8 - 4y.........eq(1) \\ \\ again \\ \: \: \: 2x + 8y = 16 \\ \: \: \: x = 8 - 4y.........eq(2) \\ \\ thus \: this \: equation \: have \: infinitely \: many \: solution.$
