Question

what is mean by elimination method.​ please answer fast

Answer 1

Step-by-step explanation:

let us take two equations

$3x - 5y = - 1 - - - - - (1) \times 1 \\ x - y = - 1 - - - - - - (2) \times 3 \\ \: \: \: 3x - 5y = - 1 \\ \: \: \: 3x - 3y = - 3 \\ ( - ) \:( + ) \: \: \: \: \: \: \: ( + ) \\ by \: changing \: the \: sign \: like \: this \: we \: get \\ - 2y = 2 \\ y = - 1 \\ 3x - 5( - 1) = - 1 \\ 3x = - 1 - 5 \\ x = \frac{ - 6}{3} \\ x = - 2 \\ this \: is \: the \: method \: to \: do \: elimination \: method \: in \: linear \: equation \\ and \: it \: is \: the \: easiest \: method \: among \: the \: three \: methods$
