Question

Find the values of x & y when
x+y=3 and X-y=1​

Answer 1

Answer:

x=2,y=1

Step-by-step explanation:

Let x+y=3 be equation 1

let x-y=1 be equation 2

Now adding equation 1 and 2 will becomes

x+y+x-y=3+1

2x=4

x=2

substituting x=2 in equation 1 we get

2+y=3

y=3-2

y=1

Answer 2

Step-by-step explanation:

x+y=3

x-y=1

x+y+x-y=3+1

2x=4

x=4/2

x=2
