Question 472276
4x − y = 2 
8x + 10y = −4
----------------
Subtract 2 times the 1st equation from the 2nd to get:
4x - y = 2
0x +12y=-8
----
Divide thru the 2nd equation by 12 to get:
4x - y = 2
0  + y = -2/3
----
Add the 2nd equation to the 1st to get:
4x + 0 = 4/3
0  + y = -2/3
-----
Divide thru the 1st equation by 4 to get:
x + 0 = (1/3)
0 + y = (-2/3)
====
That is the final answer:
