Question

What is the value of x in the solution to the following system of equations?

Answer 1

The answer is 
x _ 2y = 2
3x + y = 6     
3x _ 6y = 6 (1
3x + y = 6  (2
(1 - (2
-7y=0, y=0, so x - 2.0=2 implies x=2

Answer 2

Answer:

$x=2$

Step-by-step explanation:

we have

$x-2y=2$ ------> equation A

$3x+y=6$ ------> equation B

Multiply by $2$ equation B

$2*(3x+y)=2*6$ ------> $6x+2y=12$ -----> equation C

Adds equation A and equation C

$x-2y=2\\6x+2y=12\\--------\\x+6x=2+12\\7x=14\\x=2$

Find the value of y

$x-2y=2$

$2-2y=2$

$2y=0$

$y=0$
