3x + 2y = 14. (1)
-x. + 4y = 7. .......(2)
Multiply (2) by 3
3x + 2y = 14
-3x + 12y =21
Add both equation
14y = 35
y = 5/2
Put in (1)
3x +2(5/2) = 14
3x =14-5
3x = 9
x= 3
-x. + 4y = 7. .......(2)
Multiply (2) by 3
3x + 2y = 14
-3x + 12y =21
Add both equation
14y = 35
y = 5/2
Put in (1)
3x +2(5/2) = 14
3x =14-5
3x = 9
x= 3
