2x + y = 3<br> x = 2y - 1
Ad libitum [116K]
<span>2x+ y = 3
x = 2y - 1 
Make sure there are NO SPACES in your answer. Include a comma in your answer.
It looks like I could substitute the x=2y-1. Into 2x+y=3
2(2y-1)+y=3
4y-2+y=3
5y=5
y=1
x=2(1)-1
x=1

(1,1)
CHECK
2x+y=3
2(1)+(1)=3
2+1=3
3=3
Left hand side=Right hand side 
Check other equation 
x=2y-1
1=2(1)-1
1=1
Therefore the solution is (1,1). Since the left hand side= right hand side in each equation</span>

Henry signed up for a streaming music service that costs $14 per month. The service allows Henry to listen to unlimited music, b
stepladder [879]

Answer:

Cost for 50 songs: $64

Cost for s songs: s + 14

Step-by-step explanation:

Since it is $1 per song, if he downloaded 50 songs, it would be $50 extra dollars.

Add this to the monthly charge of 14:

50 + 14

= 64

So, the cost of 50 songs would be $64.

Now, find the cost for downloading s songs.

Each song is $1, so the cost can be represented by s + 14.

The answer is:

Cost for 50 songs: $64

Cost for s songs: s + 14

Solve for h<br> 4/5 + 3/2h = 4/3 + h
svetlana [45]

Answer:

h=16/15 or  1   1/15

Step-by-step explanation:

4/5 +3/2h = 4/3 +h

-4/3             -4/3

4/5-4/3 +3/2h = h

-3/2h                  -3/2h

4/5-4/3 =h-3/2h

convert to same denominators (left side):

12/15-20/15 = h-3/2h

-8/15 = -5/2h

h=16/15
