✍️✍️✍️

⭕️2x+7y=11

x=11-7y/2-----------(1)
⭕️5x-6y=4-----(2)

put the value of x in equation ---(2)

⭕️5x-6y=4

⭕️5(11-7y/2)-6y=4

⭕️(55-35y/2)-6y=4

⭕️55-35y-12y=8

⭕️-47y=8-55

⭕️-47y=-47

⭕️y=1

put the value of y in equation .....(1)

⭕️x=11-7y/2

⭕️x=11-7(1)/2

⭕️x=11-7/2

⭕️x=4/2

⭕️x=2

The value of
