X = 1 - y & 3x = 8 - 5y ; Find x
Plug in x into the second equation.
3x = 8 - 5y
3(1 - y) = 8 - 5y
Simplify.
3 - 3y = 8 - 5y
Add 5y to both sides.
3 - 3y + 5y = 8
Subtract 3 from both sides.
-3y + 5y = 8 - 3
Simplify.
2y = 5
Divide both sides by 2.
y = 5/2
Now, since you have the value of y, you simply plug y into the first equation.
x = 1 - y
x = 1 - 5/2
Simplify.
x = 1 - 2 1/2
Simplify.
x = -2/2 - 5/2
Simplify.
x = -7/2 AND -3 1/2

Answer:
60 percent
Step-by-.step explanation:
You need to convert 3/5 to a percentage.
This is 3*100 / 5
= 300 / 5
= 60 per cent
Know: 17.35 is equivalent to 4 burgers 3 med fries
6.09 Is equivalent to 1 burger med fries
9.34 8s equivalent to 2 burgers med fries and med drink
So what you want to do is take 6.09 and subtract it from 9.34 which is 3.25. Now 3.25 is your burger price.
What you want to do now is take your 3.25 and multiply it by 4 which would be 13. 17.35 subtract 13 would be 4.
4 divided by 3 is 1.33 which is now the price of a med fries.
now for the drink. 3.25 plus 1.33 is 4.58.
6.09 subtract 4.58 is 1.51
Now you have 3.25 as your burger
1.33 as your fries
1.52 for your drink
