Question 167834
solve the linear system by using eliminations....
8x-4y=-76
5x+2y=-16
-------------
Multiply thru the 2nd equation by 2:
 8x-4y=-76
10x+4y=-32
-------------
Add the two equation to eliminate the y-terms.
18x = -108
x = -6
--------------
Substitute that into 5x+2y = -16 to solve for y:
5*-6 + 2y = -16
-30 + 2y = -16
2y = 14
y = 7
-----------------
Solution: x=-6; y=7
