x − 2y = 2
3x + y = 6

Answer 1

@peachpi

Answer 2

@Vocaloid

Answer 3

multiply the second equation by 2

Answer 4

6x+2y=12?

Answer 5

right, now let's move to the next step

our equations are:

x-2y = 2
6x+2y = 12

add the two equations together

Answer 6

6x+4y=14

Answer 7

not quite, can you try adding 6x + x?

Answer 8

7x+4y=14?

Answer 9

close but not quite

-2y + 2y = ?

Answer 10

y

Answer 11

no, let's try this a bit differently

-2 + 2 = ?

Answer 12

0

Answer 13

right! -2+2 = 0
so what is -2y+2y = ?

Answer 14

0y

Answer 15

right! 0y, which is the same as 0

7x + 0 = 14, what is x?

Answer 16

7

Answer 17

no, please try again

7*x = 14
what is the value of x?

Answer 18

2?

Answer 19

great! x = 2

Answer 20

so thats the answer?

Answer 21

please look at the question again...

Answer 22

yes thats the answer
