Question

2. 2x + 3y = 8
4x + 6y = 7 by using elimination method
​

Answer 1

Explanation:

$2x + 3y = 8⟹⓵ \\ 4x + 6y = 7⟹⓶ \\ \\ (2x + 3y = 8) \times 2⟹⓵ \\ (4x + 6y = 7) \times 1⟹⓶ \\ \\ 4x + 6y = 16⟹⓵ \\ 4x + 6y = 7⟹⓶ \\ \\ \cancel{4x }+ \cancel{6y} = 16 \\ \cancel{4x} + \cancel{6y} = 7 \\ ( - )( - )( - ) \\ - - - - - - \\ 0 = 9 \\ - - - - - - \\ \\ Since \: \: this \: \: is \: \: \: \bf{not \: \: true} \\ Hence, \: \: the \: \: equation \: \: has \: \: \bf{no \: \: solution }$
