When solving for the value x in the equation 4(x-1) +6= 18, aaron wrote the following lines on the board: lines 1 : 4(x-1) + 6 = 18
line 2: 4(x-1)=12
lines 3: 4x-1=12
lines 4: 4x=13
lines 5: x=13/4

which property was used incorrectly when going from line 2 to line 3

The Distributive Property.

Step-by-step explanation:

4(x - 1) = 12

When distributing out the 4, it must go to all the terms within the brackets like this:

4x - 4 = 12.

4x = 16

x = 4.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
