Question

The value of ‘x’ and ‘y’ which satisfy the linear equation 2x+3y=16 are
a) x=5, y=6
b) x=2, y=5
c) x=-5, y= -2
d) x=-5, y=2​

Answer 1

I think none of the above

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

The value of ‘x’ and ‘y’ which satisfy the linear equation 2x+3y=16 are

a) x=5, y= 2

b) x=2, y=5

c) x=-5, y= -2

d) x=-5, y=2

EVALUATION

Here the given equation is

CHECKING FOR OPTION : 1

Putting x = 5 & y = 2 we get

10 + 6 = 16

CHECKING FOR OPTION : 2

Putting x = 2 & y = 5 we get

4 + 15 = 19 ≠ 16

CHECKING FOR OPTION : 3

Putting x = - 5 & y = - 2we get

- 10 - 16 = - 26 ≠ 16

CHECKING FOR OPTION : 4

Putting x = - 5 & y = 2 we get

- 10 + 6 = - 4 ≠ 16

FINAL ANSWER

Hence the correct option is a) x = 5 , y = 2
