Answer
8(40-y) + 6y =300
320 - 8y + 6y =300
-2y=-20
y=10
This leaves x to be 30.
You should spend 30 minutes on machine 1 and 10 minutes on machine 2.

Given [Missing from the question]

Required
Write a system of linear equations
The solutions to this question is open and have different solutions
Solving (8) (-6,-2)
Let the equations be: x + y and 2x - y

--- (1)

-- (2)
So, the equations are:
and 
Solving (9) (-12, 18)
Let the equations be: 3x - y and 4x + y




So, the equations are:
and 
Solving (9): (2,0)
Let the equations be: x + y and x - y




So, the equations are:
and 
Answer:
6
Step-by-step explanation:
Let's move out the tips first.
88.50-43.50=45
Now let's divide the hour earnings to find his hours!
45/7.50 = 6
