Understanding Linear Equations with Infinitely Many Solutions

The video tutorial explains how to create a linear equation with infinitely many solutions by ensuring both sides of the equation are identical for any value of x. It begins by simplifying the left-hand side and then adjusting the right-hand side to match. The tutorial demonstrates that by choosing the correct constant, the equation remains valid for any x, resulting in a true statement like -8 = -8. The process is concluded with an exercise to reinforce the concept.

What is a key characteristic of a linear equation with infinitely many solutions?

• It has the same expression on both sides for any x.

• It has a unique solution for a specific x.

• It has different expressions on both sides.

• It has no solution for any x.

What is the first step in simplifying the left-hand side of the equation?

• Adding a constant to both sides.

• Subtracting x from both sides.

• Distributing the 4 over x minus 2.

• Multiplying both sides by x.

What expression do you get after distributing 4 over x minus 2 and adding x?

• 3x - 8

• 4x + 2

• 5x + 8

• 5x - 8

What should be added to 5x on the right-hand side to ensure the equation holds for any x?

• Plus 5

• Minus 5

• Minus 8

• Plus 8

Why does making the blank a negative 8 ensure the equation is true for any x?

• Because it makes both sides identical.

• Because it makes the equation unsolvable.

• Because it simplifies the equation to zero.

• Because it creates a contradiction.

What is the result when you subtract 5x from both sides of the equation?

• 5x = 5x

• 0 = 0

• x = 0

• Negative 8 = Negative 8

What does the equation negative 8 = negative 8 signify?

• The equation has no solution.

• The equation has a unique solution.

• The equation is inconsistent.

• The equation is true for any x.

What is the final form of the equation that confirms it has infinitely many solutions?

• x = x

• 5x = 5x

• 5x - 8 = 5x - 8

• 5x + 8 = 5x + 8
