How to write an algebraic proof

The video tutorial explains how to construct a two-column proof to solve an algebraic equation. It begins with setting up the proof structure, then demonstrates solving the equation using the distributive property, simplification, and the addition property of equality. The tutorial concludes with the final steps to solve the equation and close the proof.

What is the first step in creating a proof with two columns?

What is the hypothesis in the statement 'if negative five X + 4 = 70 then X = 18'?

What property is applied when distributing -5 in the equation?

What is the next step after simplifying the equation -5X - 20 = 70?

What do we call the operation when we add the same number to both sides of an equation?

What is the final result of solving the equation -5X = 90?

What does it mean to close your proof?
