2x + y = 3
x = 2y - 1
2(2y-1)+y=3
4y-2+y=3
5y=5
y=1
x=2(1)-1

Shawna and Kai both work at the same pet store. On Monday, Shawna counts 52 birds and cats in the store. For the same animals, Kai counts 138 legs. Let b = number of birds in store
52-b = number of cats in store

2b= number of the bird's legs Kali counts
4(52-b) = number of cat's legs Kali counts
2b+4(52-b)=138 ; 2b+ 208 -4b =138 ; 2b = 208-138 ; 2b =70; b =35
52-b ; 52 -35 =17 ; There are 35 birds and 17 cats in the store

y = -x + 15
y = -(-3)+15 = 18: (-3,18) ; FAlse
y = -(0)+ 15 = 15: (0,15)
y = -(3) +15 = 12: (3,12), FAlse
A and B are False
y = -(16)+15 = -1: (16, -1) ; FAlse
y = -(15)+15 = 0: (15,0)
y = -(14)+15 = 1: (14,0)
C is also False.
