A20-a18=a1+19d-a1-17d=2d =281-97
so
d=92
Answer: The solution is (3, -2)
This means that x = 3 and y = -2 pair up together.
=====================================================
Explanation:
The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).
-----------------
As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation
y = (-5/3)x + 3
y = (-5/3)*3 + 3
y = -5+3
y = -2
The first equation is confirmed. Let's check the second equation
y = (1/3)x - 3
y = (1/3)*3 - 3
y = 1 - 3
y = -2
Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.

Hi!
We know that there are three measures and each has a different amount of notes. To find the total we add them all up.
8+16+4=28.
There were 28 total notes played in the song.
I hope I helped you!
Have a wonderful day!
(2x-5y)+(x+y)=(2x+x)+(-5y+y)=3x-4y.
therefore:
(2x-5y)+(x+y)=3x-4y
