Question

Consider the equation and its solution.

8(x-2)=64
8x-16=64
8x=80
x=10

Which property is used in the last step to find that x=10?
distributive property
addition property of equality
subtraction property of equality
division property of equality

Answer 1

last step...
8x = 80 ---divide both sides by 8 ---division property
x = 80/8
x = 10

Answer 2

Answer:

division property of equality

Step-by-step explanation:

Consider the equation and its solution.

$8(x-2)=64$

$8x-16=64$

$8x=80$

$x=10$

In the first step, 8 is distributed inside the parenthesis. So distributive property is used.

In the second step, 16 is added on both sides. So addition property is used.

In the last step , 8 is divided on both sides. So, division property of equality is used.
