Question :-

If 52x + 65y = 183 and 65x + 52y = 168 then find x + y = ?

To Find:-

Find x + y = ?

.

.

Solution:-

Here ,

${\tt{\implies{ \: 52x + 65y + 65x + 52y = 183 + 168⟹52x+65y+65x+52y=183+168}}}$

${\tt{\implies{ \: 117x + 117y = 351⟹117x+117y=351}}}$

${\tt{\implies {\: 117( x + y ) = 351⟹117(x+y)=351}}}$

${\tt{\implies {\: x + y = \cancel\dfrac { 351 } { 117 } ⟹ x + y = {117} {351} }}}$

${\tt{\implies{ \: x + y = 3⟹x+y=3}}}$

Hence ,

x + y = 3
