4x - 3y = 12<br> 4x - 5y = -4<br> Solve using Elimination
mr_godi [17]

Answer:

{ \rm{4x - 3y = 12 -  -  -  \{eqn(a) \}}} \\ { \rm{4x - 5y =  - 4 -  -  -  \{eqn(b) \}}}

• subtract eqn(b) from eqn(a);

{ \underline{ \rm{  - \binom{4x - 3y = 12}{4x - 5y =  - 4} }}} \\ { \rm{0x + 2y = 16}} \\  \\ { \rm{2y = 16}} \\  \\ { \boxed{ \tt{ \:  \: y = 8 \:  \:   }}} \\

• find x :

{ \rm{4x - 3y = 12}} \\ { \rm{4x - 3(8) = 12}} \\ { \rm{4x = 36}} \\  \\ { \boxed{ \tt{ \:  \: x = 9 \:  \: }}}
