Solution

The correct option is A True
Let 3x+2y=5 ......(1)
and 2x3y=7 ......(2)
Multiply equation (1) by 2 and equation (2) by 3
Therefore, 6x+4y=10 ....(3)
and 6x9y=21 ....(4)
Subtract equations (3) and (4), we get
13y=11
y=1113
Substitute the value of y in (1)
3x+2(1113)=5
3x2213=5
3x=8713
x=2913
x=2913,y=1113
Hence, the pair of equations are consistent.
The correct answer is A.
