Question

if 52 X + 65 y =183 and 65 x + 52 y =168 then find X + y=???​

Answer 1

Answer:

• 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

Answer 2

Answer:

Question:-

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

To Find:-

Find x + y = ?

Solution:-

Here,

52x + 65y + 65x + 52y = 183 + 168

117x + 117y = 351

117( x + y ) = 351

x + y = 351 ÷ 117

⟹x+y=3

Hence ,

x + y = 3
