The answer to this problem is A
Answer:
B. Commutative Property of Addition
Explanation:
To find out the property that would not be used in solving this equation, we solve for g.

We have applied the following:
A. Addition Property of Equality/D. Subtraction Property of Equality
C. Division Property of Equality
Therefore, the property that would not be used is:
B. Commutative Property of Addition
Distribute
remember a(b+c)=ab+ac
we can actually divide both sides by x
5(4x+8)=4(6x-10)
distribute
20x+40=24x-40
minus 20x both sides
40=4x-40
add 40 both sides
80=4x
divide by 4
20=x
Answer:
20 is 40% of 50
