Solving Equations with Distribution

The video tutorial explains how Steven solved the equation 6X = 3(X + 4). The first step involves distributing the 3 to simplify the equation to 6X = 3X + 12. The next step is to isolate the variable X by subtracting 3X from both sides, resulting in 3X = 12. Finally, dividing both sides by 3 gives the solution X = 4. The tutorial emphasizes understanding each step in the process of solving linear equations.

What is the initial equation that Steven is trying to solve?

• 6X = 3(X + 4)

• 6X = 3X + 4

• 6X = 3X + 12

• 6X = 12
