Select the correct answer.
The sum of two numbers, x and y, is 12. The difference of x and two times yis 6. What are the values of x and y?
OA X= 8, y=4
OB.
x= 10. y= 2
Ocx= 18, y= -6
OD. x= 20. y=-8

work is pictured and shown

x= 10. y= 2

Step-by-step explanation:

From the first statement :

And from the second statement :

combining the two equations we have :

.......................... equation 1

.......................... equation 2

solving the system of simultaneous linear equation by substitution method , from equation 1 , make the subject of the formula , that is

........................... equation 3

substitute   into equation 2 , then we have

Therefore :

substitute into equation 3 to find the value of x , that is

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
