Answer:
Please check the explanation below.
Step-by-step explanation:
Some of the properties are defined as:
- <em>Distributive property</em>
 
a(b+c) = ab+ac
For example,
suppose a=1, b=2, c=3
1(2+3) = 1(2) + 1(3)
5 = 2+3 = 5
- <em>Subtraction property of Equality</em>
 
if (a=b), then a-c = b-c
For example, 
suppose a=1, b=1, c=3
if a = b ⇒ 1 = 1
then a-c = b-c ⇒ 1-3 = 1 - 3  ⇒ -2 = -2
- <em>Addition property of Equality</em>
 
if (a=b), then a+c = b+c
For example, 
suppose a=1, b=1, c=3
if a = b ⇒ 1 = 1
then a+c = b+c ⇒ 1+3 = 1+3  ⇒ 4 = 4
- <em>Multiplicative property of Equality</em>
 
if (a=b), then a×c = b×c
For example, 
suppose a=1, b=1, c=3
if a = b ⇒ 1 = 1
then a×c = b×c ⇒ 1×3 = 1 × 3  ⇒ 3 = 3
- <em>Division property of Equality</em>
 
if (a=b), then a÷c = b÷c
For example, 
suppose a=1, b=1, c=3
if a = b ⇒ 1 = 1
then a÷c = b÷c ⇒ 1÷3 = 1 ÷ 3  ⇒ 1/3 = 1/3
Let's solve the given equation using the above properties.
5(x+10) = 20        Given
5x+50 = 20          1) Distriburive property ∵ a(b+c) = ab+ac
5x = -30               2) Subtraction property of Equality ∵ if (a=b), then a-c = b-c
x = -6                    3) Division property of Equality  ∵ if (a=b), then a÷c = b÷c
          
 
        
             
        
        
        

I think it is this and if not I tried to help
