Answer:
-5/6= -0.8333
And
8/3=2.67
On the number line they will be
X+y=2 (label equation one)
x-y=4 (label equation two)
y=-x+2 (equation one rearranged, label this equation equation three)
sub 3 into 2
x-(-x+2)=4
x+x-2=4
2x-2=4
2x=6
x=3
sub x=3 into equation one
3+y=2
y=-1
therefore x=3 and y=-1
Answer: 19.65
Step-by-step explanation:
all you need to do is add 850.99 and 129.36 to get 980.35
then subtract 980.35 and 1000 and you get your answer
