Question

Solve the following eq by elimination method​

Answer 1

$\huge{ \underline{ \sf{Given : }}} \\ \\ \sf{x - y = 1 \: \: \quad \longrightarrow \:( Equation \: 1) } \\ \sf{x - 3y = 1 \: \: \quad \longrightarrow \: (Equation \:2) } \\ \\ \huge{ \underline{ \sf{to \: find: }}} \\ \bf{value \: of \: x \: and \: y} \\ \\ \\ \huge{ \underline{ \sf{method : }}} \\ \sf{ \: \: \: x - y = 1} \\ \sf{ \underline{( - )x - 3y = 1}} \\ \sf{2y = 2} \\ \implies \boxed{ \sf{y = 1}} \\ \\ \sf{x - y = 1} \\ \sf{ \implies{ \boxed{ \sf{x = 2}}}}$

For graph, you can substitute values of x and y and find solutions
