Solve a simple liteeral equation by using division property of equality ex 21, D=rt; r

The video tutorial explains how to solve the equation 'distance equals rate times time' for the variable R. It begins by introducing the equation and the goal of isolating R. The instructor then describes the process of undoing the multiplication of R by T through division. The final solution is presented as R equals distance divided by time. The tutorial concludes with a summary of the steps taken to solve for R.

What is the initial equation that needs to be solved for R?

• Distance equals rate times time

• Time equals distance times rate

• Rate equals distance times time

• Distance equals time divided by rate

What operation is used to isolate R in the equation?

• Division

• Multiplication

• Subtraction

• Addition

Why do we divide by T to solve for R?

• To multiply T on both sides

• To cancel out the multiplication by T

• To add T to both sides

• To subtract T from both sides

What is the final form of the equation after solving for R?

• R equals D times T

• R equals D divided by T

• R equals D plus T

• R equals T divided by D

What is the purpose of rewriting the equation as R equals D divided by T?

• To introduce a new variable

• To make it more complex

• To simplify the equation

• To verify the solution
