<PRE><B>Question 810536</B>
i need help with row operations the problem is 4y=2x+4
-x=-2-y
---------
Rearrange::
x - y = 2
2x-4y = -4
-------------
Subtract 2 times the 1st row from the 2nd row to get::
x - y = 2
0 -2y = -8
---------
Divide the 2nd row by -2 to get::
x - y = 2
0 + y = 4
----------
Add the 2nd row to the 1st to get:
x + 0 = 6
0 + y = 4
--------
Solution:
x = 6 ; y = 4
