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?
A. x = 8, y = 4
B. x = 10, y = 2
C. x = 18, y = -6
D. x = 20, y = -8
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....
