1.	The sum of the real numbers are x and y is 11. their difference is 3. What is the value of xy?
Answer» LET the numbers be x and y. Given Sum of the numbers = 11 => x + y = 11 Difference of the numbers = 3 => x - y = 3, x>y Solving, we get, $x+y=11\\\underline{x-y=3}\\\underline{\underline{2x=14}}$ $\implies x = 7\\y = 4$ $\boxed{\boxed{\bold{Therefore, \ the \ value \ of \ xy = 4 * 7 = 28}}}}}$

Answer»

LET the numbers be x and y.

Given

Sum of the numbers = 11

=> x + y = 11

Difference of the numbers = 3

=> x - y = 3, x>y

Solving, we get,

$x+y=11\\\underline{x-y=3}\\\underline{\underline{2x=14}}$

$\implies x = 7\\y = 4$

$\boxed{\boxed{\bold{Therefore, \ the \ value \ of \ xy = 4 * 7 = 28}}}}}$
