1.	Check which of the following are solutions of an equation x+2y=4(1).(√2,-3√2)
Answer» Answer: ( X, y ) = ( √2, - 3√2 ) Here, x = √2 y = 3√2 x + 2y = 4 √2 + 2 ( 3√2 ) = 4 √2 + 6√2 = 4 7√2 ≠ 4 Therefore, ( √2, - 3√2 ) is not a SOLUTION of x + 2y = 4.

Check which of the following are solutions of an equation x+2y=4(1).(√2,-3√2)

Answer»

Answer:

( X, y ) = ( √2, - 3√2 )

Here,

x = √2

y = 3√2

x + 2y = 4

√2 + 2 ( 3√2 ) = 4

√2 + 6√2 = 4

7√2 ≠ 4

Therefore, ( √2, - 3√2 ) is not a SOLUTION of x + 2y = 4.
