Question

The sum of two numbers, x and y, is 12. The difference of x and two times y is 6. What are the values of x and y?

Answer 1

Hey,
It is given that x+y=12 and,
x-2y=6
Therefore the value of x & y will be
x+y=12
-x+2y=6 (Changing signs)
--------------
0+3y=6
--------------
=> 3y=6
=>y=6/3
=>y=2
To find value of x ,
x+y=12
x=12-2
x=10
Therefore , value of x=10 and y=2
( option=>B.)
Hope this helps you....
