WHAT did you copy/paste? I'll guess you meant
3x-2y = 4
4x-3y = 7
multiply the 1st by 3 and the 2nd by 2 and you get
9x-6y = 12
8x-6y = 14
now subtract to get rid of y ...
For the system
{
3
x
−
2
y
=
4
4
x
−
3
y
=
7
, which is the solution to the system?
A.
(
−
2
,
−
5
)
B.
(
2
,
−
5
)
C.
(
−
2
,
5
)
D.
(
2
,
5
)
