6x + 4y = 8
-4y = 12
6x + 4y = 8
y = 12/-4 = -3
6x + 4(-3) = 8
y = -3
6x -12 = 8
y = -3
x = (8+12)/6 = 10/3
y = -3 i guess

</span>James works as a waiter.
He served food with the following price
=> 23.59 dollars
=> 40.65 dollars
=> 30.50 dollars
=> 15.68 dollars
Let’s add this altogether:
=> 23.59 + 40.65 + 30.50 + 15.68
=> 110.42 the total of the ordered food.
Now, James received a tip of 17.67 dollars. Find the interest rate of his tip.
=> 110.42 * .50 = 55.21, thus the interest rate of tip is less than 50%
=> You can do trial and error to get the correct rate,
=> 110.42 * .16 = 17.67, thus he received 16% tip</span>
