Answer:
3x+4=5
Step-by-step explanation:
3x+4=25
3x=21
x=7
Answer:
(3, -1)
Step-by-step explanation:
The easiest way to solve this system of equations is by elimination:
3x + y = 8
2x - y = 7
Add the two equations together:
(3x + 2x) + (y - y) = (8 + 7)
5x = 15
x = 3
Substitute x back into the equation:
2x - y = 7
2(3) - y = 7
6 - y = 7
- y = 1
y = -1
The fourth option, (3, -1)
1 case of note cards = 20 packs
1 pack = 50 note cards
50 x 20 = 1000 note cards in one case.
1000 / 10 = 100
Each person will receive 100 note cards.
Hope this helps!! :)
