Answer:13.6%
Step-by-step explanation: I got the same problem and pressed give up.
Answer: x = (2 y)/5 - 6/5 , y = (5 x)/2 + 3
Solve for x:
2 y - 5 x = 6
Subtract 2 y from both sides:
-5 x = 6 - 2 y
Divide both sides by -5:
Answer: x = (2 y)/5 - 6/5
Solve for y:
2 y - 5 x = 6
Add 5 x to both sides:
2 y = 5 x + 6
Divide both sides by 2:
Answer: y = (5 x)/2 + 3
