-1y+34 is the answer because the x's cancel themselves out  y=-34   <-ANSWEr

anonymous · Answer

my choices are 
(-4, -3)
(-3, -4)
(4, 3)
(3, 4)

anonymous · Answer

start by putting all variables on one side of the equal sign, numbers on the other

anonymous · Answer

the first answer choice is going to be ur answer im pretty sure

anonymous · Answer

first one could be 
$$4x-3y=-7$$ then leave the second one as $$-4x-4y=28$$

anonymous · Answer

now solve by adding 
$$4x-3y=-7\
-4x-4y=28$$ add and the $x$ drops out, leaving 
$$-7y=21$$ and so $y=-3$

anonymous · Answer

since you only have once choice with $y=-3$ pick that one

anonymous · Answer

Oh I see now!
But beside the rule-out thing (since it's multiple choice), I would do this, right?:

-4x - 4(-3) = 28
-4x + 12 = 28
-4x = 16
x = -4
