What is the missing reason for line 8in this proof

Answer 1

On line 8 in this proof, all they have done is expanded LZ = 3(3) to LZ = 9 by multiplying 3 and 3 together to get 9. I assume that's all you were asking about, but let me know if you have any other questions.

I hope this helps!

Answer 2

The value of x is 3.

How to solve the equation?

We have 4 ways of solving one-step equations: Adding, Substracting, multiplication, and division. If we add the same number to both sides of an equation, both sides will remain equal.

LZ =3x = 9

3x = 9

x = 9/3

x = 3

What is an example of an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.
