Answer 4

substitute x and y for each pair
then solve if you get equal sides then order pair is a solution

Answer 5

\[\huge\rm 5x-\frac{ y }{ 3 }=13\]
substitute (x,y) for (2,-9)
replace x with 2
and y with -9

Answer 6

as above. if the substitution (x,y) makes the equation true then (x,y) is a solution.

Answer 7

\[10-\frac{ -2 }{ 3}=13\]

Answer 8

y = -9

Answer 9

y= -9
(2,-9)

Answer 10

ok so then the answer is D?

Answer 11

did you try 2nd one ?

Answer 12

oh right i have to do that on lol :)

Answer 13

yes substitute (x,y) for (3,-6)

Answer 14

\[15-\frac{ -6 }{ 3 }=13\]

Answer 15

right?

Answer 16

looks good what did you get at left side ?

Answer 17

um well -6/3=-2 so then 15+2does not equal 13 right

Answer 18

perfect!

Answer 19

yea can you help me with one or two more please x)

Answer 20

i'll try

Answer 21

Answer 23

same steps

Answer 24

so A is wrong

Answer 25

B is wrong

Answer 26

c is right and D is wrong so C is the answer

Answer 27

why do you think C is correct ?? :=)

Answer 28

because 4*1*7=28+1=36 and 4*7*1+8=36 too

Answer 29

good work!
