3x + 2y = 6 ⇒ -3x - 2y = -6
-x + y = -2 ⇒ <u>-3x + 3y = -6</u>

-5 -5
y = 0
3x + 2(0) = 6
3x + 0 = 6
<u> - 0 - 0</u>

x = 2
(x, y) = (2, 0)
Hmm...this is difficult. The first thing I can think of is the relationship between age and time.

Answer:
<em>The employees will work for 1 hour, will earn $5 per hour and will be paid $5</em>
Step-by-step explanation:
<u>System of Equations</u>
The number of hours the employees work is x.
And the hourly wage that they are paid is y. The store manager is willing to pay the employees a wage given by the equation
10y-30x=20
The business owner states that the employees should be paid a wage given by the equation
6y+30x=60
Adding both equations we have:
16y = 80
Dividing by 16:
y = 80/16 = 5
Substituting into the first equation:
10*5-30x=20
Operating and simplifying:
50-30x=20
50 - 20 = 30x
30x = 30
x = 30/30 = 1
Thus, the employees will work for 1 hour, will earn $5 per hour and will be paid $5
