Answer:
1.
y = -3x -3 (the graph is a straight line)
m = -3
b = -3
y = 2x + 2
m = 2
b = 2
2.
2x - y = 6
x + y = 6
_______
3x = 12
3x/3 = 12/3
x = 4
Plug x into the equation to solve for y.
2(4) - y = 6
8 - y = 6
- y = 6 - 8
- y = -2
y = 2
Your solution is ( 4, 2).
3. No the solution is ( 10 , -11/2)
- 2x - 4y = 2
3x + 4y = 8
__________
x = 10
- 2 (10) - 4y = 2
- 20 - 4y = 2
- 4y = 22
- 4y/ 4 = 22/4
y = -11/2
Bonus:
4x + 3 ( 1787 - x) = 5792
4x + 5361 - 3x = 5792
x + 5361 = 5792
x = 431 (reserved seat tickets)
Minus 1787 with 431 which is 1,356 general admission tickets.
Answer: 431 reserved seat tickets and 1,356 general admission tickets!
Hope this helps!
