Answer:
The system of linear equations and the solution for the system is the value. It creates all of the equations true. 2 variables or 2 equations this is the point where the two graphs intersect.
Step-by-step explanation:
Its kina complicated...if you still don't understand don't worry i don't either:/
They are basically like groups. Take -3x+2x , Just do -3 +2 = -1 and then just add the x. So -1x. Next you have -5y+10y . Just do -5 + 10 = 5 and remember to add the x on so your final answer should be -1x + 5y

hope this helped
Answer:
x = # of 5 cent coins
y = # of 50 cent coins
x+y=25
.05x+.5y=7.1
y=25-x
(.05x+.5(25-x)=7.1)100
5x+50(25-x)=710
5x+1250-50x=710
-45x=-540
x=12
You have 12, 5 cent coins and 13, 50 cent coins.
