1st step common denominator
3x +y/ 6 = 2
3x -y /9= 1
2nd step take the denominators to after the equal sign they’ll change to multiplication
The system will be
3x +y = 12
3x -y = 9
Now add the 2 systems
6x = 21
x= 21/6= 7/2
Then you substitute the value x in one of the equations
3x +y =12
3(7/2) +y =12
21/2 +y =12
y= 12-(21/2)
Y=3/2
And done hope you understand
