Answer 2

Answer:

x= 1 ; y =1

Step-by-step explanation:

Let 3x+y =a & 3x-y =b

1/a +1/b =3/4 (1)

1/2a- 1/2b=-1/8 (2)

by multiplying 1/2 in equation (1)

1/2a + 1/2b =3/8 (1)

by adding equation equation (1) and (2)

1/2a+1/2a = 2/8

2/2a = 1/4

1/a =1/4

a=4

by substituting u value in (1)

1/a +1/b =3/8

1/b+1/4 =3/4

1/b= 3/4-1/4=2/4=1/2

b=2

again solving the value of b and a

3x+y=4---------->(3)

3x-y=2----------->(4)

by adding (3) and (4)

6x=6

x=1

by substitution x=1 in equation (3)

y=1

Answer

x= 1 and y =1
