What is the reason for each strip on the solution of the equation?
Pani-rosa [81]

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:

2x = -4(x-3)

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

2x=-4x+12

Now, Applying addition property of equality:

Adding +4x on both sides

2x+4x=-4x+12+4x\\6x=12

Now, Applying Division property of Equality:

Divide both sides by 6:

\frac{6x}{6}=\frac{12}{6}\\x=2

So, Answer will be:

Step 1: Given

Step 2:  Distributive Property

Step 3: Addition Property of  Equality

Step 4: Division Property of  Equality
