X + 3 Y :6.........(1)
2x - 3 y :12..........(2)
x + 3y : 6
2x-3y : 12
--------------
3x : 18
x: 18 ÷ 3
x:6
substituting the value of x in equation (1) we get
x + 3y : 6
6 + 3y :6
3y: 6-6
y:0/3
y:0
2x - 3 y :12..........(2)
x + 3y : 6
2x-3y : 12
--------------
3x : 18
x: 18 ÷ 3
x:6
substituting the value of x in equation (1) we get
x + 3y : 6
6 + 3y :6
3y: 6-6
y:0/3
y:0
