Question

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

Answer 1

Answer:

3

Step-by-step explanation:

52x + 65y = 183        ...(1)

65x + 52y = 168        ...(2)

Adding (1) and (2):

   52x + 65y = 183  

   65x + 52y = 168

  117x + 117 y = 351

⇒ 117x + 117y = 351

⇒ 117(x + y) = 351

⇒ x + y =351/117

     ∴  x + y = 3

Answer 2

Question:-

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

To Find:-

• Find x + y = ?

Solution:-

Here ,

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

$\tt\implies \: 117x + 117y = 351$

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

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

$\tt\implies \: x + y = 3$

Hence ,

• x + y = 3
