Let "x" be a substitute for "a number"
1/3(x)=x-12 Multiply by 3
x=3x-36 Get n onto the same side of the equation
2x=36 Divide by 2
x=18
That's your answer.
Answer:

Step-by-step explanation:
Take out 3x from both sides:
5x - 3x = 3x - 3x
2x = 0
2x + 9 = 1
Take out 9 from both sides:
9 - 9 = 1 - 9
0 = -8
Divide 2 from both sides:


Answer:
B
Step-by-step explanation:
It all starts whether the Knave of Hearts tells the truth or not. You can decide yourself.
Hearts: H
Clubs: C
Diamonds: D
Spades: S
If H lies, C tells the truth, therefor D lies. So S tells the truth
If H tells the truth, C lies. Therefore D tells the truth and S lies
Step 1: Given
Step 2: Distributive Property
Step 3: Addition Property of Equality
Step 4: Division Property of Equality
Step-by-step explanation:
We need to match the reason with the correct step in the equation.
Equation:
Given:

Applying Distributive property a(b+c)=ab+ac

Now, Applying addition property of equality:
Adding +4x on both sides

Now, Applying Division property of Equality:
Divide both sides by 6:

So, Answer will be:
Step 1: Given
Step 2: Distributive Property
Step 3: Addition Property of Equality
Step 4: Division Property of Equality
