Answer:
A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It must be a solution for both to be a solution to the system. Hope this helps.

Step-by-step explanation:
Answer:
Okay, so a bit of math is involved, along with steps.
Step-by-step explanation:
Kyra invested $400 at 3% for 3 years. meaning 3% of $400 is 12. 400+12=
Year 1: $412
3% of 412=12.23+412=
Year 2: $424.23
3% of 424.23=12.7+423.23=
Year 3: $435.93
Kyra made $35.93 in investments.
Lishsawn invested $500 at 4% for 2 years. Meaning, 4% of $500 is 20. 500+20
Year 1: $520
4% of 520=20.8+520
Year 2: $540.8
Lishawn made $40.8 dollars in investments. Meaning that Lishawn made $4.87 more dollars
Answer:
24 premium tickets were sold.
Step-by-step explanation:
Let :
Deluxe ticket = x
Regular tickets = x + 78
Premium tickets = y
x + (x + 78) + y = 208
4x + 2(x+78) + 10y = 714
2x + y = 208 - 78
4x + 2x + 156 + 10y = 714
2x + y = 130 - - - - - (1)
6x + 10y = 558 - - - - (2)
Now we can solve the simultaneous equation using elimination method :
From (1)
y = 130 - 2x
Put y = 130 - 2x in (2)
6x + 10(130 - 2x) = 558
6x + 1300 - 20x = 558
- 14x = 558 - 1300
-14x = - 742
x = 742 / 14
x = 53
Put x = 53 in y = 130 - 2x
y = 130 - 2(53)
y = 130 - 106
y = 24
4 x 213 = 4 x (200 + 10 + 3) = 852
