Y=x+8 x+y=2 substituion

X = -3

y = 5

Step-by-step explanation:

Substitute x + 8 for y

x + x + 8 = 2

2x + 8 = 2

2x = -6

x = -3

y = x + 8

y = -3 + 8

y = 5

this is false ^.^ lol

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
