Two step equations example
2x + 2 = 10
Inverse operation. What is the opposite of +2?
-2 is!
Apply that to both sides to balance it
2x + 2 = 10
- 2 -2
2x = 8
2x/2 = 8
We divided because it is the opposite of multiplication.
2x/2 = 8/2
x = 4
Answer: x = 4

sry I just wanted the points I'm in middle school so I don't know this stuff either
Answer: 11
============================================
Explanation:
Point C is the circumcenter of triangle PQR. This means that we can draw a circle centered at C that goes through points P, Q and R at the same time. This circle has a special name: circumcircle.
The segments PC, RC and QC are all radii, so they are the same length. Pick two of the given expressions and set them equal to one another. Then solve for x
I'm going to pick the expressions for PC and RC
PC = RC
3x+7 = 5x-15
5x-3x = 7+15
2x = 22
x = 22/2
x = 11
The probability of rolling factors of 3 would be 1/3
