Solving Equations and Inequalities

This video tutorial covers solving equations using multiple steps. It begins with an overview of the process and then demonstrates various examples, including solving equations with fractions, decimals, and variables on both sides. The video also shows how to check solutions using a graphing calculator.

What is the first step in solving equations with multiple steps?

• Check the solution

• Clear fractions or decimals

• Isolate the variable

• Add or subtract terms

In the first example, what operation is used to isolate the variable term?

• Addition

• Subtraction

• Multiplication

• Division

How do you clear a fraction in an equation?

• Add the denominator to both sides

• Multiply every term by the common denominator

• Subtract the numerator from both sides

• Divide every term by the numerator

What is the result of multiplying 93 by 15 in the context of solving an equation?

• 1395

• 15X

• 31/5

• 6.2

When solving equations with variables on both sides, what is a crucial step?

• Divide both sides by a constant

• Multiply both sides by the variable

• Subtract the variable term from one side

• Add the same number to both sides

In the example with variables on both sides, what is the final solution for X?

• X = 5

• X = -5

• X = 3

• X = -3

What is the purpose of using a graphing calculator in solving equations?

• To solve for Y

• To check the solution

• To graph the equation

• To find the derivative

How can you verify the solution of an equation using a graphing calculator?

• By storing the solution and checking the equation

• By solving for another variable

• By calculating the derivative

• By graphing the equation

What is the simplified form of 16/12?

• 3/4

• 2/3

• 1/2

• 4/3

In the final example, what is the solution for X when 24 is divided by -2?

• X = 12

• X = -12

• X = 6

• X = -6
