When you have a system of equations like this, the solution will be a coordinate, so it will have an x point and a y point. To find the solution's x coordinate you first want to add the equations together.
x + 3y = 5
x - 3y = -1
x + x = 2x
3y - 3y = 0
5 + (-1) = 5 - 1 = 4
So now we have 2x = 4
Just solve for x in this simple one-step equation by dividing each side by 2 to isolate the variable.
2x / 2 = 4 / 2
x = 2
The x coordinate of the solution is 2.
Now, to find the y coordinate we will substitute our x value (2) into either of the original equations.
I'll choose x + 3y = 5
We now know that x = 2, so replace x with 2.
x + 3y = 5
2 + 3y = 5
3y + 2 = 5
(subtract 2 from each side)
3y + 2 - 2 = 5 - 2
3y = 3
(divide each side by 3)
3y / 3 = 3 / 3
y = 1.
So, we've found that the x coordinate of our solution is 2, and the y coordinate is 1/
The solution is (2, 1)

Let me know if you need help understanding anything and I'll try to explain as best that I can.
Jesus is always the answer
The answer is 6x to the power of 2 +48x
The Mean is the value of all the numbers in a data set added together and divided by the amount of numbers there are for example the mean of the set 2,5,8,9 is 6.
The median is the middle values of all the numbers. If there are 2 medians, you usually have to add them both and divide by 2 to get the actual median
The mode is the number(s) that show up the most in the data set. for example, the mode of the data set 2,2,3,4,4,4,6,9 is 4, because it is repeated 3 times.
hope this helped!
