3x - y = 9
-2x -y = -11 |* -1
3x - y = 9 } +
2x+y = 11
-------------
5x / =20
x=20:5
x=4
3x -y = 9
3*4 - y = 9
12 - y= 9
y=12-9
y=3
(4,3) is the solution
X= - 4/5
Answer for number 10
The amount spent is an illustration of subtraction and proportions
The amount left in his earnings is $414.25
<h3>How to determine the amount left in his earnings?</h3>
The given parameters are:
Rate = $22 per hour
Time = 40 hours
So, the total earnings is:
Total = $22 * 40
Evaluate
Total = $880
He spent half on bills.
So, we have:
Bills = 0.5 * $880
Bills = $440
He buys a video game for $25.75
