Answer:
24
Step-by-step explanation:
2(54-6x)=73-7x
108-12x=73-7x
108-73=-7x+12x

Answer:
the download cost for a song is $1 and $11 for a movie
Step-by-step explanation:
According to the questions, the following equations are as follows:
Let us assume the song be x
And, the movies be y
So,
20x + 13y = $163.........(i)
13x + 13y = $156........(ii)
Now solve substract second equation from the first equation
7x = $7
x = $1
And the y value is
20 + 13y = $163
13y = $163 - $20
13y = $143
y = $11
Hence, the download cost for a song is $1 and $11 for a movie
