10 (x + 3) is the answer i believe
So you know that:
2x+y=14+y
and
5x-y=x+13y
Here you have two equations with two unknown variables:
If you isolate x from the second equations you get:
x=(7/2)y
Insert that in the first equations and solve for y:
2*(7/2)y+y=14+y
y=2
Insert that value for y in one of the two equations (i chose the first):
2x+2=14+2
x=7
Therefore x=7
Hope that helped.
Actually you could start with isolating x, and then insert that in one of the two equations.
Answer:
-4.6
Step-by-step explanation:
-2.3-2.3=-4.6
The independent variable (the one they want) is the # of hours worked, since that determines the price.
