Solving Multi-Step Equations

Mr. Bohor explains how to solve multi-step equations involving fractions and decimals. He demonstrates three examples: solving with fractions using two methods, handling equations with multiple fractions, and solving equations with decimals by eliminating them. The video emphasizes simplifying equations and using basic operations to isolate variables.

What is the main focus of the video tutorial?

• Learning about algebraic expressions

• Understanding basic arithmetic operations

• Solving multi-step equations with fractions and decimals

• Solving equations with variables

Which of the following is NOT a basic rule for solving multi-step equations?

• Multiply both sides by zero

• Undo addition and subtraction

• Undo multiplication and division

• Simplify the equation

In the first example, what operation is performed first to solve the equation 2/3 * N - 6 = 22?

• Divide both sides by 2

• Subtract 6 from both sides

• Add 6 to both sides

• Multiply both sides by 2/3

What is the value of N in the equation 2/3 * N = 28?

• 56

• 42

• 28

• 14

In the alternative method for the first example, what is the purpose of multiplying both sides by 3?

• To eliminate the variable

• To simplify the equation

• To get rid of the fraction

• To add fractions

What is the result of multiplying 3 * 2/3 N in the alternative method?

• N

• 2N

• 3N

• 6N

In the second example, what is the least common denominator used to eliminate fractions?

• 25

• 10

• 15

• 20

What is the final value of X in the second example after solving the equation?

• -25/8

• -3

• 1/8

• 0

In the third example, what is the purpose of multiplying both sides by 1000?

• To divide the equation

• To add decimals

• To eliminate decimals

• To simplify the equation

What is the final value of M in the third example?

• 9.95

• 12.75

• 80

• 35
