Question

Value of x and y for equations x+y =3 and X - 2y = 3 is :

Answer 1

Answer:

x+y=3

x-2y=3

subtract both eqns

x+y-x+2y=0

3y=0

y=0

sub in eqn 1

x+y=3

x+0=3

x=3

Answer 2

Given:

The equations x+y =3 and X - 2y = 3

To find:

Value of x and y for equations x+y =3 and X - 2y = 3

Solution:

From given, we have,

The equations x  + y = 3 and x - 2y = 3

Now consider,

x  + y = 3 ....... (1)

x - 2y = 3 ...... (2)

subtract equations (1)  and (2)

y = 0

substitute the value of y in any one of equations (1) or (2)

x + 0 = 3 ....... (1)

x = 3

x - 2 (0) = 3 ...... (2)

x = 3

Therefore, the values of x and y are 3 and 0 respectively.
