Answer 2

#7

Answer 3

2x = y + 12
3x = 19 + y

eliminate the x, then solve for y

Answer 4

-y=12
-y=19?

Answer 5

2-y=12
3-y=19?

Answer 6

hmmm... as the alternative way
2x = y + 12
3x = 19 + y
------------ (-)
what would happen if the 1st equ subtracted with the 2nd equ ?

Answer 7

-X=-7?

Answer 8

yes,
so x = ?

Answer 9

x=7!

Answer 10

that's right
now subtitute x=7 to one of the equation above

Answer 11

let, we take the 1st equation :
2x = y + 12
put x = 7, then solve for y

Answer 12

it means :
2x = y + 12
2 * 7 = y + 12
14 = y + 12

now solve for y

Answer 13

y=2!

Answer 14

perfect thanks again

Answer 15

that's right
welcome :)
