Solving Linear Equations Concepts

Mr. Holcomb presents a lesson on solving linear equations using the SADNET method. The video covers four examples, demonstrating how to combine like terms, use inverse operations, and check solutions. Each example is solved step-by-step, with explanations of the properties used and checks for correctness. The lesson concludes with a summary and a prompt to review the problem set.

What is the first step in solving a linear equation using the SADNET method?

• Dividing both sides by a variable

• Subtracting constants from both sides

• Combining like terms

• Multiplying both sides by a constant

Why is it important to combine like terms first when solving a linear equation?

• To simplify the equation and reduce the number of steps

• To make the equation more complex

• To eliminate all variables

• To increase the number of constants

What is the inverse operation of addition in solving equations?

• Multiplication

• Subtraction

• Exponentiation

• Division

What is the result of dividing a negative number by a positive number?

• Zero

• Undefined

• Negative

• Positive

What property is used to eliminate parentheses in an equation?

• Identity Property

• Distributive Property

• Commutative Property

• Associative Property

When checking a solution, what should the left and right sides of the equation be?

• Different

• Equal

• Zero

• Opposite

In the equation 2x + 3 = 7, what is the first step to isolate x?

• Add 3 to both sides

• Divide both sides by 2

• Subtract 3 from both sides

• Multiply both sides by 2

How do you handle fractions when solving a linear equation?

• Convert them to decimals

• Ignore them

• Multiply by the reciprocal

• Add them to both sides

What should you do if you have variables on both sides of an equation?

• Add them together

• Move them to one side

• Ignore one side

• Multiply them by zero

What is the purpose of checking your solution in a linear equation?

• To ensure the solution is correct

• To find a different solution

• To make the equation more complex

• To eliminate variables
