Question

find the solution of the following of the pear of linear equation 2x-y=11 and 3x+2y=13 ​

Answer 1

Answer:

x=5, y= -1

Step-by-step explanation:

2x-y=11... (I)

3x+2y= 13... (ii)

on multiplying (I) with 2 and adding (I) with (ii) we get

4x-2y=22

3x+2y= 13

__________

7x= 35

x= 5

replacing x in (I) we get

2*5-y=11

y= 10-11

y= -1

therefore, x=5, y= -1
