Question

Question 2.2. Solve by the linear combination method (with or without multiplication).

2x + 3y = 11
–4x + 2y = 2

(Points : 1)
(1, 3)
(2, 3)
(1, 2)
(1, –2)

Answer 1

what is the linear combination method?

Answer 2

multiply the first equation by -2 and then add them resulting in a cancellation of the x's

Answer 3

+2 i mean

Answer 4

then wat?

Answer 5

2x+3y=11
-4x+2y=2

2x+3y=11
-2x+y=1
--------
4y=12
Y=3

Plug in
-2x+3=1
-2x=-2
X=1

(1,3)

Answer 6

thanks

Answer 7

i have a few more

Answer 8

ok

Answer 9

?

Answer 10

U still have a question?

Answer 11

BORDEM sorry

Answer 12

yea

Answer 13

Sorry this site is very slow,

Multiply the first equation by 2, then add them to cancel the g's

Answer 14

-8g + 10h = 8
8g + 10h = -4
----------------

0 + 20h = 4
so h = 4/20 = 1/5

Answer 15

put h=1/5 into any of the equations to get the value of g.
