Question no. 85. Which point satisfies the equation 2x + 3y = 8

A: (1,4) B. (2.2) C: (-1.3) D : (-2,4)

Solution : '

( X ,Y ) = ( 1,4 )

2x + 3y

                    2(1) + 3(4) =  14  not satisfied

( X ,Y )= (2.2)

2x + 3y

                              2(2 ) + 3(2 ) =  10    not satisfied

( X ,Y )=(-1.3)

2x + 3y

2( -1 ) + 3 (3) =

-2 + 9 = 6 not satisfied

( X ,Y )=(-2,4)

2x + 3y

2( -2 ) + 3 (4) =

-4 + 12 = 8 Ans satisfied

Question no. X^2 - 36 = 0

x^2= 36

taking Square root On Boths Side
