I solved it in the picture. please take a look. step by step is shown in picture.

Answer 2

Step-by-step explanation:

1(3x+y)+1(3x-y)=3/4

3x+y+3x-y = 3/4

6x = 3/4

3x= 6×4

x = (6×4)/3

x = 2×4

x = 8

1/2(3x+y)-1/2(3x-y)=1/8

(3x+y)/2 - (3x-y)/2 = 1/8

3x+y-3x+y/2 = 1/8

2y/2 = 1/8

8×2y = 2×1

2y = 2/8

y = 2/8×2

y = 1/16

therefore, x = 8

y = 1/16
