Question

In the below system, solve for y in the first equation.

x – 3y = –6
2x – 7y = 10

1/3x + 2

-1/3x + 6

–x + 2

-1/3x + 2

Answer 1

take the first equation, and try to isolate y

Answer 2

x – 3y = –6

Answer 3

how do i do that? you're gonna have to take baby steps haha

Answer 4

aha..

Answer 5

first baby step : subtract x both sides

Answer 6

alrighty...

Answer 7

walk a bit, and show me wat u get

Answer 8

i really have no idea i'm sorry haha

Answer 9

's okay :)

Answer 10

x – 3y = –6

subtract x both sides

x – 3y = –6
-x -x

Answer 11

alright...

Answer 12

-3y = -x-6

Answer 13

oh thats what i just got

Answer 14

good, next see that -3 is attached to y

Answer 15

since we want to solve y, we need to get rid of it

Answer 16

just we do the opposite, divide both sides by -3

Answer 17

-3y = -x-6
/-3 /-3

Answer 18

y = 1/3x + 2

Answer 19

see if that makes some sense

Answer 20

oh that does make sense

Answer 21

good :)

Answer 22

so it's a right?

Answer 23
