Answer:
1 hotdog is $3.5.
1 drink is $2.
Step-by-step explanation:
18.50= 3x+4y(times 5)
25.50=5x+4y(times -3)
92.5=15x+20x
-76.5=-15x+-12y
16=-8y
2=y
18.50=3x+4(2)
10.50=3x+8
10.50=3x
3.5=x

Answer:
no solutions
Step-by-step explanation:
Given the 2 equations
y = - 7x + 8 → (1)
y = - 7x - 8 → (2)
Substitute y = - 7x - 8 into (1)
- 7x - 8 = - 7x + 8 ( add 8 to both sides )
- 7x = - 7x + 16 (add 7x to both sides )
0 = 16 ← not possible
This indicates the system has no solutions
