Hope it helps you.

Answer 2

Answer:

Let, the two numbers are x and y.

According to the first conditions,

          y+2x+2​=21​⇒2x−y=−2⟶(1)

and according to the second condition,

          y−4x−4​=115​⇒11x−5y=24⟶(2)

Multiplying equation (1) by 5 we get,

          10x−5y=−10⟶(3)

Subtracting equation (2) from equation (3),

          ⇒11x−5y−10x+5y=24+10

          ⇒x=34

Putting the value of x in equation (1),

          ⇒2×34−y=−2⇒68−y=−2⇒y=70

Hence, the required numbers are 34,70.
