Will fan and medal
Solve the following system of equations:

x − 2y = 14
x + 3y = 9

(1, 12)
(−1, −12)
(12, −1)
(12, 1)

Answer 1

X - 2y = 14
X + 3y = 9

Answer 2

are you there??

Answer 3

yes but don't get it

Answer 4

(multiply the second equation by -1)
X - 2y = 14
-1( x+ 3y = 9)

Answer 5

Now add them up, now X cancels and you have Y
- 2y - 3y = 14 - 9
-5y = 5
==> y= -1

Answer 6

Now add them up, now X cancels and you have Y
- 2y - 3y = 14 - 9
-5y = 5
==> y= -1

Answer 7

do you get it ???

Answer 8

so b would the answer

Answer 9

yes

Answer 10

well your welcome see you another time
