Solving Linear Equations with Fractions

The video tutorial demonstrates solving an equation for x by simplifying fractions, isolating the variable, and verifying the solution. It begins with the problem statement, followed by clearing fractions using the least common multiple. The instructor then isolates x by performing algebraic operations and verifies the solution by substituting it back into the original equation.

What is the initial equation given in the problem?

• x - 8 = x/3 + 1/6

• x + 8 = x/2 - 1/3

• x + 8 = x/3 - 1/6

• x - 8 = x/2 + 1/3

What is the least common multiple of the denominators in the equation?

• 12

• 3

• 9

• 6

After clearing the fractions, what does the equation become?

• 6x - 48 = 3x + 1

• 6x + 48 = 3x - 1

• 6x - 48 = 2x + 1

• 6x + 48 = 2x - 1
