Question

Which property justifies Step 3?Given: 4(x - 6) + 12 - 20Step 1: 4x - 24 + 12 = 20Step 2: 4x - 12 = 20Step 3: 4x = 32Step 4: x = 8A)Substitution PropertyB)Distributive PropertyC)Addition Property of EqualityD)Subtraction Property of Equality

Answer 1

The solution steps are given below as

`\begin{gathered} 4(x-6)+12=20 \\ step1:4x-24+12=20(distributive\text{ property\rparen} \\ step2:4x-12=20(by\text{ additon property\rparen} \\ Step3:4x=32 \\ Step4:x=8(division\text{ property\rparen} \end{gathered}`

Hence,

The final answer is ADDITION PROPERTY OF EQUALITY

Hence,

OPTION C is the right answer
