<h3>Solving a system of equations by Elimination </h3>
From the question, we are to determine the sequence of operations that would produce the correct x- or y-value of the solution to the given system of equations
The given systems of equations are
2x+y=9
x+3y=-13
- First, multiply the first equation by -3
That is
-3 × (2x+y=9)
-6x-3y=-27
- Now, add to the second equation
-6x-3y=-27
+(x+3y=-13)
-----------------
-5x = -40
Thus, we can solve for x
These sequence of operations will enable us to eliminate y and solve for x
Hence, the sequence of operations that would produce the correct x- or y-value of the solution to the system of equations is multiply the <u>first equation</u> by –3 and add the result to the <u>second equation</u> to eliminate y and solve for x. The correct option is - b)multiply the first equation by –3 and add the result to the second equation to eliminate y and solve for x

Add six to each side I think
Each school would receive 72 tickets
648 tickets / 9 schools
or
648 / 9 = 72
Answer:
Givens
- The cost of the square windows is 3 euros per meter, and 12 euros for the crystal.
<h3>If a window has 2 meters side, how much would it cost? (A)</h3>
Notice that the window is a square, that means all four sides are congruent, so it has 8 meters in total, which would cost 24 euros plus the crystal. Therefore, the total cost of a window with 2 meters side is 24+12 = 36 euros.
Specifically, the function of the cost is: 
, where 
represents meters of sides. (C)
<h3>If we paid 60 euros, the dimensions are (B)</h3>
The window has 16 meters between the four sides, which gives 5 meters per side.
The graph of the function is attached.
