Question

12x = 3 - 2y
2x + 4y = 6

Answer 1

@hartnn?

Answer 2

substitution again ?

Answer 3

Yes.

Answer 4

first , as simplification., divide 2nd equation by 2.

Answer 5

Wait i messed up. /.\ the first equation is x = 3 - 2y.

Answer 6

then, you can directly substitute that x in 2nd equation...

Answer 7

2( 3-2y) + 4y = 6 ?

Answer 8

yes, go on, solve further...if you make an error, i'll stop you and tell u.

Answer 9

I got 6 - 8y = 6, but then i added 6 and then it went to 8y = 12 .. :/

Answer 10

Hello? @hartnn?

Answer 11

you get
6-4y+4y=6
that is 6=6
which is an identity,
hence there will be infinite solutions to this system of equation.
sorry for late reply.

Answer 12

sorry, you have to make a new question...

Answer 13

But how do you get 6 = 6 ?

Answer 14

\[2( 3-2y) + 4y = 6 \\ 6-4y+4y=6 \\ 6-0=6 \\ 6=6 \\identity\]

Answer 15

Mkaii. :3 i need help on 1 more then im done.

Answer 16

sure...
