Question

X+Y=1,X-Y=3 ,Solve the following pair of linear equations​

Answer 1

Answer:

X+Y=1 ----1

X-Y=3. ----2

add 1 and 2

2X=4

X= 2

put X= 2 in eq.1

2+Y=1

Y=-1

Step-by-step explanation:

hope this helps u

Answer 2

Answer:

X = 2 and Y = 1

Step-by-step explanation:

On adding both the equations we get

X+Y+X-Y = 3+1

2X = 4

X = 2

Now put value of X in X+Y = 1

2+Y = 1

Y = 2-1

Y = 1
