What is the first step solving this equation 3x+4y+3x=12+2y-8

combine the like terms on each side (so just the two x’s need to be added together), then subtract the 2y from 4y & solve from there

3x+4y+3x=12+2y-8

    -2y            -2y

3x+2y+3x=12+-8

3x+3x=6x

6x+2y=12+-8

6x+2y=4

6x/4=1.5x

2y/4=0.5y

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
