Master Solving two step equations

The video tutorial explains how to solve two-step equations by reversing the order of operations. It covers examples involving negative variables and fractions, demonstrating techniques like rearranging terms, using reciprocals, and eliminating fractions with the least common denominator. The tutorial emphasizes understanding the operations affecting the variable and applying the properties of equality.

What is the first step in solving a two-step equation?

• Undo multiplication

• Undo division

• Undo addition or subtraction

• Identify the variable

What is the reverse order of operations used for?

• Simplifying equations

• Solving equations

• Identifying variables

• Multiplying fractions

In Example 1, what operation is performed first to isolate the variable?

• Divide by 3

• Multiply by 3

• Add 4 to both sides

• Subtract 4 from both sides

In Example 1, what is the final value of X?

• 6

• 24

• 8

• 12

How do you handle a negative variable in a two-step equation?

• Divide by -1

• Multiply by -1

• Subtract a positive number

• Add a positive number

What is the result of dividing by a negative number in Example 2?

• Zero

• Undefined

• Negative result

• Positive result

In Example 3, what is the first operation to perform when dealing with fractions?

• Add the fractions

• Divide by the numerator

• Multiply by the denominator

• Subtract the constant

In Example 3, what operation is used to undo division by 4?

• Add 4

• Subtract 4
