Solving Subtraction Equations Involving Fractions

This video tutorial teaches how to solve a one-step subtraction equation involving fractions. The process involves isolating the variable X by using the inverse operation of addition to counteract subtraction. By adding five sixths to both sides of the equation, the equation remains balanced, allowing X to be isolated. The solution is verified by substituting the value back into the original equation, confirming its correctness. The lesson concludes with a recap of the steps involved in solving such equations.

What is the first step in solving a one-step subtraction equation involving fractions?

• Isolate the variable by using the inverse operation

• Add a constant to both sides

• Divide both sides by the same number

• Multiply both sides by the same number

What is the inverse operation of subtracting five sixths?

• Dividing by five sixths

• Adding five sixths

• Multiplying by five sixths

• Subtracting five sixths

Why do we add five sixths to both sides of the equation?

• To simplify the fractions

• To eliminate the variable

• To keep the equation balanced

• To make the equation more complex

What is the solution to the equation after isolating X?

• X = 5/6

• X = 2 and 13/30

• X = 1 and 3/5

• X = 2 and 1/2

How can we verify that our solution to the equation is correct?

• By adding a different fraction to the solution

• By dividing the solution by the original equation

• By substituting the solution back into the equation

• By multiplying the solution by the original equation
