Question

What is the reason for Step 2 in the solution of the equation? 18−2x = 4x

Step 1: Given 18 = 6x
Step 2: _____ 3 = x
Step 3: Division Property of Equality Question 1
(a)Combine Like Terms
(b)Distributive Property
(c)Division Property
(d)Addition Property of Equality

Answer 1

i think b ( Distributive property) is correct answer.

Answer 2

Addition Property of Equality

Explanation:

Step 1: Given :
`8−2x = 4x`

Step 2:
`18 = 6x`

Step 3: Division Property of Equality
`3=x`

`8−2x = 4x`

Add 2x on both sides

`8−2x+2x = 4x+2x`

`8=6x`

To get step 2, add 2x on both sides

Its addition property of equality
