Question

2x + 8y = 21 6x - 4y = 14

Answer 1

• Answer:
• (x,y)=(3/31, 107/62)

Explanation:

{2x+8y=14

{216x-4y=14

{x+4y=7

{216x-4y=14

217x=21

x=3/31

2*3/31+8y=14

y=107/62

(x,y)=(3/31, 107/62)

2*3/31+8*107/62=216*3/31-4*107/62=14

14=14=14 since all of the equalities are true the order pair is the solution of the system (x,y)=(3/31, 107/62)

hope this helps :)
