As part of this month's customer appreciation, iSongs is offering every fifth customer a free song
download. Every twelfth customer gets a free video
download. How many customers in the first 200 will
receive both the free song and free video -
downloads?

Hey there!

LCM of 12 and 5= 60

Thus, in 200 customers, 3 will get both free song and video downloads.

Let me know if this helps :)

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

if you need just tell me and i will come to the rescue.
