Let's eliminate x in the system
<span>
2x-5y=-5
x+2y=11
To do this, mult. the 2nd eqn by -2:
</span> 2x-5y=-5
-x-4y=-22
---------------
-9y= -27. This yields y = 3.
Now subst. 3 for y in either of the original equations to determine x.
Write your answer as an ordered pair: ( ? , 3).

Answer:
113
Step-by-step explanation:
we need to know how much Lou has first !
so we have to do 682 / 6 which = 113
then 113 / 4 = 28.2
28.2 is how much Lou has
so we will go back and multiply the 4
28.2 x 4 =113
