Answer:
6r+7=13+7r
6r+7=7r+13
6r+7−7r=7r+13−7r
−r+7=13
−r+7−7=13−7
−r=6
= 
r=−6

2. The Addition property of Equality statest that:
If
, then 
3. The Subtraction property of Equality statest that:
If
, then 
4. The Division property of Equality statest that:
If
, then 
5. The Multiplication property of Equality statest that:
If
, then 
Given the equation:

You must solve for "g" in order to find its value:
- Apply the Distributive property:

- Apply the Addition property of Equality adding 30 to both sides of the equation:

- Apply the Division property of Equality dividing both sides by 2:
