Solving Linear Equations with Fractions

The video tutorial explains how to solve a simple linear equation involving fractions. It begins by introducing the equation 28/3 = 1/3 + x and discusses the need to isolate the variable x. The tutorial demonstrates subtracting 1/3 from both sides to maintain equality, simplifying the equation to x = 9. Finally, it verifies the solution by substituting x back into the original equation, confirming that both sides are equal.

What is the initial equation given in the problem?

• x = 28/3 + 1/3

• 1/3 = 28/3 + x

• 28/3 = 1/3 + x

• 28/3 = x - 1/3
