Let x be the number of songs downloaded.

Each song is $1.29; the total cost would be found by multiplying the cost by the number of songs, or 1.29x.

This cannot be more than 20, so we set this less than or equal to 20:

1.29x ≤ 20.

__To solve this, we divide both sides by 1.29: __

≤ ;

x ≤15.5.

We__cannot download half of a song__, so we round this down to 15 (although the number rounds up mathematically, he would not have enough money to download 16 songs). This means he can download at most 15 songs.

QUESTION POSTED AT 28/03/2020 - 12:37 PM

If you want an answer to question: You can make the equations equal to each other and solve for x. So, since the y values are the same, we can do

(+x)5x+6 = -x-7. (+x)

(-6)6x+6= -7(-6)

(1/6) x 6x= -13 x (1/6)

x= -13/6

Substitute −13/6 for x in y=5x+6:

y=5x(−13/6) + 6

y = -29/ 6.

**y= -29/6 and x= -13/6**

(+x)5x+6 = -x-7. (+x)

(-6)6x+6= -7(-6)

(1/6) x 6x= -13 x (1/6)

x= -13/6

Substitute −13/6 for x in y=5x+6:

y=5x(−13/6) + 6

y = -29/ 6.

X+y=95

2x+y=120

filling the first in into the second, gives:

y = 95-x

2x+95-x=120 => x+95=120 => x=25, y=70

2x+y=120

filling the first in into the second, gives:

y = 95-x

2x+95-x=120 => x+95=120 => x=25, y=70
