Ok, so first off you need to remember that your goal is to get x alone.
How do you do this? Well, let's get rid of that pesky negative ten, shall we?
The opposite of a negative is positive, so you can move negative ten to the other side of the problem by adding ten. Make sure that you do operations on both sides. Once you add, you have 3x=18. When a number is right next door to an x, it means it is being multiplied. To get rid of the three, divide by three on both sides. Now your get x=6, which is your answer. Hopefully, I explained this well! :D

Answer:
Step-by-step explanation:
To find the slope of the given line, slope is the rise divided by the run of a line.
Slope = 
Picking points (4, 18) and (8, 12)
Now;
x₁ = 4
y₁ = 18
x₂ = 8
y₂ = 12
Slope = 
= 
=
To prove this statement, start with a picture of alternate interior angles that are assumed to be congruent, but don't assume the lines are parallel. In the picture below, assume . Prove that (two parallel bars indicate parallel lines). If corresponding angles are congruentthen lines are parallel.
