if
x + y = 9
x - y = 5
then
$\frac{ {6( {x}^{2} + {y}^{2}) } }{12xy} = ?$
​

Answer 1

Step-by-step explanation:

x+y=9. ( 1 )

x-y=5. (2)

add both of the above equations

2x=14

x=7

y=9-x. ( from eq 2)

y=9-7. ( x=7)

y=2

now,

$6( {x}^{2} + {y}^{2} ) \div 12xy$

on dividing numerator and denominator by 6 we get :-

$({x}^{2} + {y}^{2} ) \div 2xy$

insert values of x and y

$( {7}^{2} + {2}^{2} ) \div 2 \times 7 \times 2$

$(49 + 4) \div 28$

=53/28
