Question

If (X+y,3y) = (7,15) find X,y

Answer 1

Answer:

The answer of your question is (2,5)

Step-by-step explanation:

x+y = 7 ....(i)

3y = 15

Then, y = 5

Use this y value in no. (i) equation

So, x+5 = 7

Then, x = 2

So, the value of (x,y) = (2,5)

Answer 2

Question :-

If (x+y,3y) = (7,15) Find x and y .

Solution :-

we have ; (x+y,3y) = (7,15) [ Given ]

Now on comparing ,

we get ,

x + y = 7 and 3y = 15

=》3y = 15 =》 y = 5 .

Now put the value of y in other equation ,

x + 5 = 7

=》x = 2 .

Answer : -

So ; ( x , y ) = ( 2 , 5 )
