To solve this problem, the first thing we have to do is regroup the terms so that we can then subtract, simplify, subtract, and finally simplify again.
But first we must know.
<h3>¿What are the equations?</h3>Equations are those mathematical equalities divided between two expressions which are called members and separated by their equal sign, in which known elements and unknown or unknown data appear, related by mathematical operations.
<h3>We solve the problem:</h3>- 8n - 7 = -12 + 3n
- 8n - 7 = 3n - 12
- 8n - 7 - 3n = -12
- 5n - 7 = -12
- 5n = -12 + 7
- 5n = -5
- N = -1
Now we must check our results.
8n -7 = -12 + 3n
8 × - 1 - 7 = -12 + 3 × - 1
- 8 - 7 = - 12 - 3
- 15 = - 12 - 3
- 15 = - 15
So, our results are correct, the answer is n = - 1

Answer:
Step-by-step explanation:
1. You just plot the points
2. To plot the line you have to find the slope and y-intercept
Slope = =
=
Slope =
Y-intercept =
Y-intercept: y - 15 = (x - 2)
y - 15 = + 15
Add 15 to both sides
y = x + 30 this is the equation of the line.
So you start with the starting point and then the slope!
