​

Answer 1

Answer:

x=49/23,y=27/23

Step-by-step explanation:

given: 6x+7y-11=10

and. 5x+2y=13

6x+7y=21 -------(1)

5x+2y=13--------(2)

multiply with 5 on both sides for equation (1)

and multiply with 6 on both sides for equation (2)

then, 30x+35y=105

30x+12y=78

-. -. -

--------------------------

0 +23y= 27

--------------------------

y= 27/23

then x=49/23

hope this helps you
