Answer:
x=38/7 y=106/14
Step-by-step explanation:
3x-2y=6........equation1
2x+y=11...........equation2 ×2
=>4x+2y=22
therefore, by adding equation 1&2
4x+2y=22
3x-2y= 6
_________
7x =38
x =38/7
so,substituting the value in equation 1,we get
3×38/7-2y=6
=114/7-2y=6
= -2y=6-144/7
= -2y=(42-144)/7
= -2y= -106/7
= y=106/14
