Answer:
Given
X + Y = 6 …………………….. ( 1 )
3 X - y = 4 ………………….. ( 2 )
Solution : Adding equations 1 and 2 , we have
4 x = 10
Dividing both sides by ‘ 4 ‘ , we have
4 x / 4 = 10 / 4
=> x = 5 / 2
=> x = 2.5
Putting x = 2.5 in equation ‘ 1 ‘ , we have
2.5 + Y = 6
Subtracting ‘ 2.5 ‘ on both sides, we have
2.5 - 2.5 + Y = 6 - 2.5
=> y = 3.5
So, x - y = 2.5 - 3.5
x - y = - 1 Answer
