Ok so u have to set them equal to 180 bc they r supp lines so 1.15+x=180 sub 15 from both sides x=165
2.28+x-4=180 combine like terms 28-4=24 rewrite 24+x=180 den sub 24 from both sides x=156
I will put the rest in the comments if you still don't know

Answer:
52 tickets cost $10 and 18 tickets cost $12
Step-by-step explanation:
10x+12y=804. (1)
x+y=70. (2)
From (2)
x=70-y
Substitute x=70-y into (1)
10x+12y=804
10(70-y)+12y=804
700-10y+12y=804
700+2y=804
2y=804-700
2y=104
y=104/2
y=52
Recall
x+y=70
x+52=70
x=70-52
x=18
52 tickets cost $10 and 18 tickets cost $12
