Solve the system of equations.
y = 3x
x + y = -32

x = − 8  , y = − 24

Step-by-step explanation:

x+3x= -32

x=-8

y=3(-8)

y=-24

x=-8, y=-24

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
