Jonathan uploaded some original songs and also some pictures. alissa uploaded four times as many songs, but only uploaded twice
as many pictures. jonathan uploaded 11 items while alissa uploaded 24. how many songs did jonathan upload? (1 point) 1 4 6 10
1 answer:
X is the number of songs and Y the number of pics
our 2 equations will be - X+y=11 & 4x+2y=24
consider x=11-y
Lets replace x in 2:
=4(11-y) +2y=24
=44-4y+2y=24
=44-24= 4y-2y
=20= 2y
=Y=20/2
=Y=10
Lets replace y in 1
=X+10=11
=X=11-10
=X=1
