Does: 2(4x + 10) = 8x + 20 has, One, None, Infinitely Many Solutions? You must show your work.

Infinitely many solutions

Step-by-step explanation:

2(4x+10)=8x+20

8x+20=8x+20

It is the same on both sides, which means infinitely many solutions.

one solution

Step-by-step explanation:

2( 4 + 1 0 ) = 8 +2 0   = 2 8 + 2 0

Subtract  

from both sides of the equation

Simplify  

Subtract  8  from both sides of the equation

Simplify

Divide both sides of the equation by the same term

Simplify

Solution   = − 5 /2

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
