Question

(vii) The solution of the equations
x-y=2 and x+y=4 is:​

Answer 1

Answer:

I hope this is clear to you

Answer 2

Answer:

Solution :

The given simultaneous equations are:

x-y =2 ..............(1)

x+y =4 .............(2)

Adding (1) and (2) , we get

x-y =2 .............(1)

x+y =4 ............(2)

+ + +

_______

2x= 6

x =3

Substituting the value of x in (1) , we get

3-y = 2

y = 3-2

y=1

The solution of the the given simultaneous equations are : (x,y) = (3,1)
