Understanding One-Step Subtraction Equations with Negatives

In this video, Mr. J explains how to solve one-step subtraction equations involving negative numbers. The process is similar to solving equations with positive numbers, focusing on isolating the variable using inverse operations. Two examples are provided: solving J - 14 = -10 and 18 = G - (-3). The video emphasizes the importance of maintaining balance in equations by performing the same operation on both sides. It also highlights the concept of subtracting a negative as adding a positive. The video concludes with a recap of the methods discussed.

What is the first step in solving one-step subtraction equations with negatives?

• Divide both sides by the variable

• Subtract the same number from both sides

• Add the same number to both sides

• Multiply both sides by zero

In the equation J - 14 = -10, what operation is used to isolate J?

• Subtraction

• Addition

• Multiplication

• Division

What is the solution to the equation J - 14 = -10?

• J = -10

• J = -4

• J = 4

• J = 14

How can you verify the solution to an equation?

• By asking a friend

• By substituting the solution back into the original equation

• By checking with a calculator

• By guessing

In the equation 18 = G - (-3), what does subtracting a negative number do?

• Keeps the value the same

• Multiplies the value by two

• Increases the value

• Decreases the value

What is the solution to the equation 18 = G - (-3)?

• G = 15

• G = 21

• G = -3

• G = 18

What is an alternative way to think about subtracting a negative number?

• As adding a positive number

• As subtracting a positive number

• As multiplying by zero

• As dividing by two

How can you rewrite the equation 18 = G - (-3) to make it simpler?

• 18 = G + 3

• 18 = G - 3

• 18 = G * 3

• 18 = G / 3

What is the inverse operation of subtraction?

• Subtraction

• Multiplication

• Division

• Addition

What should you always remember to do when solving equations?

• Only change one side of the equation

• Keep the equation unbalanced

• Perform the same operation on both sides

• Ignore the variable
