Answer 1

need help

Answer 2

Solve the system algebraically.

y = 3 -1/2 x
3x + 4y = 1

What is the value of x?

-11
17/2

Answer 3

the first equation tells you how to write y in terms of x

i.e wherever you see a y you could replace it with (3-x)

so in th second equation you should write it, making that change (put 3-x where you see y)

Answer 4

but in from of x is a 1/2 there

Answer 5

I am looking at your first question - you should start a new thread for each question

Answer 6

ok i will

Answer 7

wait - did you correct the post in your second posting?

is the correct equation got I/2 x in it?

Answer 8

yes

Answer 9

ok - but the same solution applies as I described above

wherever you see y in the second equation you can replace it with 3 - 1/2 x)

Answer 10

but is the answer

Answer 11

did you just want the answer?

Answer 12
