Question

what is 3x-5y=9,x=-1,0,1

Answer 1

Substitute each x value into the given equation:
3(-1)-5y=9 solve for y
-3-5y=9
-5y=12
y=-12/5 Do that process for the remaining two x values 0 & 1

Answer 2

Can you take it from here

Answer 3

i dont understand

Answer 4

which part

Answer 5

What do i do with the Y????

Answer 6

how do u get -5y = 12?

Answer 7

3(-1)-5y=9
-3-5y=9
-3+3-5y =9+3 added 3 to each side to get -5y by itself
0-5y=12 simplified -3+3=0
-5y=12 simplified 0-5y=5y

Answer 8

-5y=12
-5y/-5=12/-5 getting y by itself
y=-12/5 so when x is -1, y is -12/5 (-1,-12/5)

Answer 9

Now let's figure out 3x-5y=9 when x=0
3(0)-5y=9 substituted in where I saw the x
0-5y=9 simplified
-5y=9 simplified
-5y/-5=9/-5 divided by -5 to get y by itself
y=-9/5 when x is 0, y is -9/5 (0,-9/5)

Answer 10

Now, you solve the equation when x=1

follow the same process

Answer 11

ok thxxxx

Answer 12

do you understand

Answer 13

nope

Answer 14

OK...x=1

substitute into the equation 3x-5y=9 put 1 in where you see an x
3(1)-5y=9
do you understand this part

Answer 15

ya

Answer 16

OK...simplify this...multiply out the 3(1)

3(1)-5y=9
3-5y=9 Understand this part

Answer 17

yes

Answer 18

whats the next part???

Answer 19

after 3(0) part

Answer 20

the 3(0) means to multiply 3 and 0, which gives us 0

Answer 21

still there

Answer 22

Later

Answer 23

you got a lot of patience DSS :) Cheers to you
