Solve a one step equation using division with a decimal

The video tutorial explains how to isolate a variable in an equation. The teacher demonstrates the process of isolating the variable on the right side of the equation and then flipping it. The tutorial covers the steps to solve the equation by undoing multiplication through division, leading to the final solution. The teacher verifies the solution by substituting it back into the equation to ensure both sides are equal.

What is the primary goal when isolating a variable in an equation?

• To add more variables to the equation

• To make the variable the subject of the equation

• To eliminate all numbers from the equation

• To multiply the variable by a constant

If a variable is being multiplied by a number, what operation should be used to isolate it?

• Multiplication

• Subtraction

• Division

• Addition

What is the result of dividing a number by itself?

• Negative one

• One

• The original number

• Zero

What is the value of 'd' that satisfies the equation after isolating it?

• -2.4

• 2.4

• -1.25

• 1.25

How can you verify that the solution to an equation is correct?

• By adding the solution to both sides of the equation

• By substituting the solution back into the equation

• By multiplying the solution by the variable

• By dividing the solution by the variable
