The solution of the given equations is: (-1.5, 1.5)
Step-by-step explanation:
Linear equation usually represents a straight line. When a system of two liner equations is given, the point of intersection of lines represented by both equations is the solution of the system of equations.
We will plot the lines of both equations and find their point of intersection (Picture Attached)
We can see in the picture that two lines intersect at (-1.5, 1.5)
Hence,
The solution of the given equations is: (-1.5, 1.5)

For step one, it’s Graph A because it’s going through the origin
For step two, the rate of change is -3, you can find the answer by using the rise/run method by going down three and going right once.
For step 3, the dividing method doesn’t work because -1 divided by 2 isn’t 0.
For step four, go to the point (-2,-4) and from that point draw a line up three units. From there draw a line right two units, and you should stop at -1 on the 6-axis
I hope this helped!
Answer:
y =8.7
Step-by-step explanation:
y + 8.5 = 17.2
Subtract 8.5 from each side
y +8.5 -8.5 = 17.2 -8.5
y =8.7

Answer:
probability the student plays both instruments is [ 
]
<h2>
<u>
Explanation</u>
:</h2>
students who play both instruments = total students - flute players - piano players - students who play neither instruments
students who play both instruments
→ 31 - 4 - 14 - 7
→ 6 students play both instruments.
probability:
