Solving Literal Equations and Concepts

The video tutorial covers solving literal equations, which involve rearranging formulas to isolate a specific variable. It explains the use of inverse operations and PEMDAS in reverse to solve equations. Examples include solving D = RT for R, Y = MX + B for B, M/D = V for M, and more complex equations like the area of a trapezoid and E = MC^2. The tutorial emphasizes understanding the process of isolating variables and applying mathematical operations correctly.

What is a literal equation?

How do you solve the equation D = RT for R?

• Multiply both sides by T

• Divide both sides by T

• Add T to both sides

• Subtract T from both sides

What is the result of solving D = RT for R?

• R = D * T

• R = D - T

• R = D / T

• R = D + T

In the equation Y = MX + B, what is the first step to solve for B?

• Add MX to both sides

• Multiply both sides by MX

• Subtract MX from both sides

• Divide both sides by MX

What is the result of solving Y = MX + B for B?

• B = Y / MX

• B = Y + MX

• B = Y - MX

• B = Y * MX

How do you solve the equation M/D = V for M?

• Subtract D from both sides

• Multiply both sides by D

• Divide both sides by D

• Add D to both sides

What is the result of solving M/D = V for M?

• M = D * V

• M = D - V

• M = D / V

• M = D + V

In the trapezoid area formula, what is the first step to solve for B1?

• Multiply both sides by 2

• Divide both sides by 2

• Add B2 to both sides

• Subtract B2 from both sides
