Question 220282
How do you do problems like 
2x-3y=-14  
3x+4y=-4 using elimination?
---------
Multiply the 1st Eq by 3; Multiply the 2nd Eq. by 2
6x-9y = -42
6x+8y = -8
-------------
Subtract the 1st from the 2nd:
17y = 34
y = 2
-----
Substitute to solve for "x":
2x - 3*2 = -14
2x = -8
x = -4
---------------------------
Solution: (2,-4)
