Question

x − y = 10
x + y = 6

(−2, 8)

(−8, 2)

(8, −2)

(8, 2)

Answer 1

Hint: add the equations to get

x-y = 10
x+y = 6
---------
2x+0y = 16

so

2x = 16

Answer 2

so if you rearrange you see
x=10+y
x+6-y

so 10+y=6-y
solve for y and sub back into the equation to find x :)

Answer 3

sorry @jim_thompson5910 my computer doesn't seem to show me when other people respond lol

but yes @Marcus980 jim is right!!

Answer 4

that's ok sarahusher

Answer 5

Answer 6

y = -2 is correct

Answer 7

(−2, 8)

(−8, 2)

(8, −2)

(8, 2)

Answer 8

remember coordinates are in the form
(x,y)
so just sub in your values :)

Answer 9

So (-2,8)

Answer 10

double check which comes first, x then y
if x=8
y=-2
(x,y)

Answer 11

I sse What You Are Talking About It The 8,-2

Answer 12

Yes! Good work
