Multiple choice

brad needs to solve the equation 2(4x-2)=20 his solution is
shown below in the picture which which three properties did
brad use to solve the equation

a distributive property

b subtraction property

c division property

d addition property

Answer : Three properties brad use to solve the equation are:

A) Distributive property

C) division property

D) Addition property

Step-by-step explanation :

Associative property of addition : It is a property when we are adding numbers then we can group the numbers in any combination.

For example : a+(b+c) = (a+b)+c

Associative property of multiplication : It is a property when we are multiplying numbers then we can group the numbers in any combination.

For example : a×(b×c) = (a×b)×c

Commutative property of addition : It is a property in which we can add numbers in any order.

For example : a+b = b+a

Commutative property of multiplication : It is a property in which we can multiply numbers in any order.

For example : a×b = b×a

Distributive property : The distributive property multiply a sum by multiplying each addend separately and then add the products.

For example : a×(b+c) = (a×b) + (a×c)

The given expression is:

2(4x-2) = 20

First we have to use distributive property.

(2 × 4x) - (2 × 2) = 20

8x - 4 = 20

Now we have to use addition property.

8x - 4 + 4 = 20 + 4

8x = 24

Now we have to use division property.

x = 3
