x=8-y
where x is 0,7 and 8
find y

Question

campbell_st · Answer

use substitution

0 = 8 - y

can you find y..?

anonymous · Answer

is it -8?

anonymous · Answer

use y=8-x (on rearrangement and then put the values of x as 0,7,8 as 8,1,0)
thus the pair is (0,8) (7,1) and (8,0)

campbell_st · Answer

so the 1st ordered pair is (0, -8)

just repeat the process for x = 7 and x = 8

anonymous · Answer

(0,-8)
(-7,1)
(8,0)

and as @matricked  has so kindly done... you don't to to gain an understanding... you can just copy his answers...

not quite 

7 = 8 - y

whats y..?

anonymous · Answer

(7,1)

campbell_st · Answer

correct, 

lastly 

8 = 8 - y

find y..

anonymous · Answer

i mean (7,-1)

campbell_st · Answer

nope its just 1... 

7 = 8 - 1

so y = 1

anonymous · Answer

@campbell_st  i hope u mistyped the first ordered pair (0, -8)

campbell_st · Answer

thanks @matricked

campbell_st · Answer

and I did mistype the 1st solution its (0, 8) and the 2nd you found is (7, 1)
