Thank you for the opportunity to help you with your question!

8x+2y=2/3

y=3x-2


substitute y=3x-2 in  8x+2y=2/3

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

8x+6x-4 = 2/3

14x = (2/ 3)+4

14x = (2 + 12) /3

14x = 14 /3

x = 1/3.................................ANSWER


now substitute this value of  x = 1/3 in  y=3x-2

y=3x-2

y = 3 * ( 1/3) -2

y = 1 - 2

y = -1..................................ANSWER


point is (1/3 , -1)

x = 1/3

y = -1



Please let me know if you need any clarification. I'm always happy to answer your questions.....thank you
