Given :-

  • sum of two numbers = 35
  • difference of two numbers = 13

To Find :-

  • find the numbers ?

Solution :-

let the two numbers be x and y

then,

  • x + y = 35 .......(i)
  • x - y = 13 ........(ii)

now, adding eq.(i) and (ii)

 \bold{ :  \implies \: x  \:  \cancel{ + \:   y } \: +  \: x  \cancel{  \: - \:   y }= 35 + 13} \\  \\  \bold{: \implies  2x = 48 } \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \bold{ : \implies x =   \cancel\frac{48}{2} }  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\  \\  \bold{: \implies x = 24}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

now, subtract eq.(ii) from eq.(i)

 \bold{:  \implies \cancel{  \:  x }\:  +  \: y \: \cancel{ - \:  x } \:  +  \: y = 35 - 13} \\  \\  \bold{:  \implies 2y = 22} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:   \\  \\  \bold{ : \implies y =   \cancel\frac{22}{2}  } \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \bold{ : \implies y = 11 }\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

so, value of x is 24 and value of y is 11

hence, the two numbers are 24 and 11
