Answer:

The value of X=4,y=7

Step-by-step explanation:

Given that,

3x+2y-26=0 ---------(1)

6x+y-31=0 -----------(2)

From equation (1)and(2),

3x+2y=26 ---------(3)

6x+y=31 ---------(4)

{equation(3)×2}-{equation (4)}

6x+4y=52

6x+ y=31

__________

(-) 3y=21

=)y=21÷3

=)y=7

From equation (3),

3x+(2×7)=26

=)3x+14=26

=)3x=26-14

=)3x=12

=)X=12÷3

=)X=4

Answer: X=4 and y=7.
