Solving Literal Equations with Multiple Variables

What is a literal equation?

• An equation with only one variable

• An equation with more than one variable

• An equation with no variables

• An equation with only constants

In the equation f = D/e, what operation is performed to isolate F?

• Subtraction

• Addition

• Multiplication

• Division

What is the first step to solve for M in the equation y = mx + b?

• Divide both sides by y

• Subtract b from both sides

• Multiply both sides by x

• Add b to both sides

After subtracting b from both sides in the equation y = mx + b, what is the next step to isolate M?

• Subtract y from both sides

• Multiply both sides by x

• Divide both sides by x

• Add y to both sides

In the equation H = mJ + 2K, what is the first step to solve for K?

• Divide both sides by 2

• Add mJ to both sides

• Subtract mJ from both sides

• Multiply both sides by 2

After subtracting mJ from both sides in the equation H = mJ + 2K, what is the next step to isolate K?

• Multiply both sides by 2

• Subtract H from both sides

• Divide both sides by 2

• Add H to both sides

What is the final form of K in the equation H = mJ + 2K after isolating it?

• K = H - 2mJ

• K = H + mJ / 2

• K = 2(H - mJ)

• K = (H - mJ) / 2

What is a key characteristic of literal equations?

• They have no variables

• They cannot be rearranged

• They have only one variable

• They can be rearranged to solve for a specific variable

What should you remember about literal equations?

• They cannot be solved

• They are always linear

• They can be solved using only addition

• They have more than one variable

What is the final message of the video?

• Literal equations are easy

• Math is difficult

• Practice makes perfect

• Always be kind
