Solve 3x+ k = c for x.

x=(c-k)/3

Step-by-step explanation:

First, subtract k from both sides of the equation to get: 3x=c-k

Next, divide both sides by 3 to get x by itself=> 3x/3=c-k/3

The threes on the left side cancel, giving you x=(c-k)/3

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
