Tutorial-Solve a proportion when the variable is in denominator and numerator ex 16, (3+2x)/(3–2x)=3

The video tutorial demonstrates how to solve an equation involving X. It begins by setting up the equation and discussing incorrect methods to avoid. The instructor then explores different methods to solve the equation, focusing on using the cross product. The tutorial emphasizes the importance of using parentheses and distributive properties when multiplying expressions. Finally, the instructor solves for X, showing how to simplify and reduce the answer to a fraction.

What is one incorrect method mentioned for solving the equation 2X/3 - 2X = 3?

• Multiplying both sides by the denominator

• Dividing out the threes or the two Xs

• Using the cross product

• Adding 6X to both sides

Which method is preferred by most students for solving the equation?

• Subtracting 3 from both sides

• Using the cross product

• Dividing out terms

• Adding variables to one side

What is the result of applying the cross product to the equation?

• 3/4

• 8X = 6

• 2X/3 = 3

• 3 + 2X = 9 - 6X

What is the next step after getting 3 + 8X = 9 in the equation?

• Multiply both sides by 3

• Subtract 3 from both sides

• Add 6X to both sides

• Divide by 8

What is the final reduced form of the solution for X?

• 5/6

• 3/4

• 1/2

• 2/3
