Question

Choose the equivalent system of linear equations that will produce the same solution as the one given below.

6x + 2y = -6
3x - 4y = -18

12x + 4y = -12
15x = -30

8x + 4y = -4
14x = -10

6x - 8y = -36
-6y = -42

6x - y = -15
3y = 9

Answer 1

Will Fan and Medal! Thanks!

Answer 2

Please help! @gerryliyana

Answer 3

I think so far that the answer is C

Answer 4

check first

6x + 2y = -6 | times 2|
3x - 4y = -18

then

12x + 4y = -12
3x - 4y = -18
--------------------+
15x = -30

Answer 5

Thank you! Could you help me with one more?

Answer 6

of course go ahead

Answer 7

sorry

Answer 8

my computer is going crazy

Answer 9

ok i'll wait you

Answer 10

Solve the system of equations.

2x - 5y = 3
x - 3y = 1

(4, 1)

(5, 2)

(7, 2)

(9, 3)

Answer 11

I think it is D

Answer 12

2x - 5y = 3
x - 3y = 1 |times 2|

then

2x - 5y = 3
2x - 6y = 2
--------------- -
y = 1

then check fo x by using x - 3y = 1

x - 3y = 1
x = 1 + 3y
x = 1 + 3(1)
x = 4

Answer 13

So it should be A

Answer 14

Oh, ok.. I get where I went wrong..

Once again, thank you soo much!

Answer 15
