In this exercise we have to use subtraction knowledge to calculate the final value of the equation, like this:
Letter C
<h2>What is subtraction?</h2>It is a mathematical operation in which it is possible to find a quantity by decreasing one number by another, it is opposed to addition, being represented by the minus sign.
So make the calculus we have:

Hi!
We can use <u>point-slope form </u>to solve this.
<em> and </em>
<em> will be from one of the points.</em>
<u>First, we have to find </u><u>, the slope. We can use the slope equation to get this.</u>
<em>Plug in your points:</em>
Your slope is
<u><em>Now plug points and slope into point-slope equation. We will use (8, 4).</em></u>
Now, if you want to get it into y = mx + b form, you have to solve for y:
Your equation is

Answer:
X = - 4
Step-by-step explanation:
Given in problem
- x -4x - 7 = 5 -2x
Or, -5x - 7 = 5- 2x
Or, -5x + 2x = 5 + 7
Or, -3x = 12
Or, x = -
∴ X = - 4 Answer
