Question

lf x=a, y=b is the solution of the pair of equation x-y=2 and x+y=4 then what will be value of a and b.​

Answer 1

Answer:

a=3, b=1

Step-by-step explanation:

given pairs of eqns are

x-y=2 and x+y=4

adding eq 1 and 2 we get,

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

x-y+x+y=6

2x= 6

x=6/2 =3

substituting the value of x in eqn 1

3-y=2

= y=3-2 =1
