50 - 5n = 15
if you need to find the number n then
50 - 5n = 15
-5n = -35
n = 7

This is your answer ☺️☺️☺️
a. The first variable is x and the second variable is y.
b. The equations are
and ![x-y=8.](https://tex.z-dn.net/?f=x-y%3D8.)
Step-by-step explanation:
Step 1:
The first step is to define the variables. The variables can be any two symbols, letters, characters, etc.
Here let the first variable be x and the let the second variable be y.
So the variables are defined as x and y.
Step 2:
The sum of the given variables is 12.
The first variable + the second variable = 12,
![x+y=12.](https://tex.z-dn.net/?f=x%2By%3D12.)
The difference between the two variables is 4.
The first variable - the second variable = 4.
![x-y=4.](https://tex.z-dn.net/?f=x-y%3D4.)
Step 3:
If we add both the equations we get,
and ![y=4.](https://tex.z-dn.net/?f=y%3D4.)
x = 8 and y = 4.
15, if you plot the points, then seperate the x and y into two seperate lines, you can create a 3,4,5 triangle to find the distance between the points.
Answer:
y = 6x - 11
Step-by-step explanation:
An arithmetic sequence is a linear function. This means it steadily increases or decreases through addition/subtraction by a constant amount. Here the sequence grows by adding 6 each time.
-11 + 6 = -5
-5 + 6 = 1
1 + 6 = 7
etc....
Since this is linear, its equation has the form y = mx + b where m is the slope and b is the y-intercept. The slope is m = 6 and b = -11.
y = 6x - 11
