Question

Consider the equation and its solution.

8(x-2) = 64
8x-18-84
8x = 80
X=10
Which property is used in the last step to find thatx-10?
distributive property
addition property of equality
subtraction property of equality
division property of equality

Answer 1

division property of equality

Explanation:

The property used in the last step to find x = 10 in the expression is the division property of equality.

8(x-2) = 64

8x-18 = 84

8x = 80

x = 10

In 8x = 80 ;

Division property of equality was used to find the value of x.

The property states that when we divide both sides by a non-zero value, the two sides remains the same.
