Answer:
ANSWER
Let 3x+2y=5 ......(1)
and 2x−3y=7 ......(2)
Multiply equation (1) by 2 and equation (2) by 3
Therefore, 6x+4y=10 ....(3)
and 6x−9y=21 ....(4)
Subtract equations (3) and (4), we get
⇒13y=−11
⇒y=−
13
11
Substitute the value of y in (1)
⇒3x+2(−
13
11
)=5
⇒3x−

=5
⇒3x=

87
⇒x=

29
∴x=
13
29
,y=− 13
11
Hence, the pair of equations are consistent.
The correct answer is A.

Answer:
1.
3x -2y =5
3x = 5 +2y
3x = 7y
x= 7y/3
x=2y.
2. 2x-3y=7
2×=7+3y
2x = 10y
x=10y/2
×=5.
I think it's answer I am sure ...
but hope its help you
