Solving Linear Equations Steps

Mr. Buffington teaches how to solve equations by isolating variables, focusing on two-step equations. He explains the property of equality and inverse operations, using examples to demonstrate solving equations, including those with negative numbers and like terms. A challenge problem with variables on both sides is also presented.

What is the main goal when solving equations?

• To multiply all terms by zero

• To eliminate all numbers

• To make both sides of the equation zero

• To find the value of the variable

What is the purpose of isolating a variable in an equation?

• To make the equation more complex

• To add more variables

• To find the value of the variable

• To eliminate the variable

What does the property of equality state?

• You can only add numbers to both sides of the equation

• You must do the same operation to both sides of the equation

• You can ignore the operations on one side of the equation

• You can add different numbers to each side of the equation

What is the first step in solving the equation 3x - 5 = 19?

• Divide both sides by 3

• Subtract 5 from both sides

• Add 5 to both sides

• Multiply both sides by 3
