Answer:
x=7
Step-by-step explanation:
This problem uses vertical angles! I'm sure you know this but just in case I will explain. Whenever there are two angles that are across from each other in a junction of two straight lines, they are perfectly equal! In this problem, the angles 6x-7 and 4x+7 are the same angle, so those equations have to have the same answer. In order to solve it, you need to write the equations like this:
6x-7=4x+7
From there you can solve for x. I will write my process here:
2x-7=7
2x=14
x=7
Just writing those vertical angle equations as equalities of each other should give you the answers you are looking for!
Answer:
You need to get x by itself
(x = 1)
Step-by-step explanation:
1. Expand.
-12x - 3 - 8x = - 16 - 7x
2. Simplify
-20x - 3 = -16 - 7x
3. Add 20x to both sides.
-3 = -16 -7x + 20x
4. Simplify.
-3 = -16 + 13x
5. Regroup terms.
-3 = 13x - 16
6. Add 16 to both sides.
-3 + 16 = 13x
7. Simplify.
13 = 13x
8. Divide both sides by 13.
1 = x
9. Switch sides
x = 1
I believe it is No it’s not
