Understanding Equations and the Story of X

The video tutorial covers solving equations by telling the 'story of X'. It includes two examples: one with the equation 2(X + 1) - 3 = 5 and another with (3X - 4)/2 = 7. Each example is solved by constructing the equation step-by-step and then solving it by reversing the operations. The solutions are verified by substituting the values back into the original equations.

What is the first step in telling the story of X for the equation 2(X + 1) - 3 = 5?

• Divide X by 2

• Subtract 3 from X

• Add 1 to X

• Multiply X by 2
