Question

pair of linear equations x+y=9 and x-y=1, the value of x and y are

Answer 1

Answer:

Step-by-step explanation:

X+Y=9 ....(1)

X-Y=1 ....(2)

Y=9-X ... From (1)

Substituting the value of the Y in equation (2)

X-(9-X)=1

X-9+X=1

2X=10

X=5

Substituting the value of X in equation (1)

5+Y=9

Y=4

Therefore the value of the Y is 4 and the value of the X is 5.
