The answer is going to be 14.125 in decimal form
2/8 of an hour is 15,and 2/6 of an hour is 20 minutes. 20-15 is 5 minutes
4x + 3y = 54 (1)
3x + 9y = 108 (2)
Multiply (1) by (-3)
-12x - 9y = -162
3x + 9y = 108
---------------------add
-9x = -54
x = 6
plug x = 6 into (1) to find y
4(6) + 3y = 54
24 + 3y = 54
3y = 30
y = 10
Answer
(6 , 10)
