Solving One-Step Equations with Fractions and Decimals

The video tutorial provides practice in solving equations with variables. It begins with solving the equation 1/3 + A = 5/3 by isolating the variable A. The next example involves solving K - 8 = 11.8 by adding 8 to both sides to isolate K. The final example demonstrates solving 5/13 = T - 6/13 by adding 6/13 to both sides to find T. The tutorial emphasizes the importance of maintaining equality by performing the same operation on both sides of the equation.

What is the equation given in the first example?

• A + 1/3 = 5/3

• 5/13 = T - 6/13

• 1/3 + A = 5/3

• K - 8 = 11.8
