Answer 3

i got x=3/4

Answer 4

how did you get that?

Answer 5

2x+y=3
4x=6-2y
y=3-2x
4x=6+3-2(3-2x)
4x=6+3-6+4
4x=9-6+4
4x=3+4
x=7/4

Answer 6

You should have this

2x + y = 3

y = 3 - 2x

------------------

4x=6-2y

4x=6-2(3-2x)

4x=6-6+4x

4x - 4x = 6-6

0x = 0

0 = 0

So there are infinitely many solutions

Answer 7

so x and y both have infinite solutions
