Solving a one step equation with subtraction

The video tutorial explains how to solve one-step equations, particularly focusing on handling double negatives. It begins by introducing the concept and then demonstrates how to rewrite equations with double negatives. The tutorial emphasizes the importance of isolating the variable by performing opposite operations, such as subtracting when a number is added to the variable. The final section covers the calculation steps to solve the equation completely.

What should you do when you encounter a double negative in an equation?

• Ignore the negative signs

• Add the numbers together

• Rewrite the equation

• Multiply the numbers

In the context of solving equations, why might you circle a variable?

• To change its value

• To highlight it for later

• To remember to add to it

• To focus on operations affecting it

What is the purpose of subtracting the same number from both sides of an equation?

• To add complexity

• To isolate the variable

• To change the variable

• To make the equation longer

What is the result of subtracting 20 from both sides of the equation in this problem?

• 20

• -76

• 0

• 56

What is the final value of the variable J in the equation?

• 0

• 56

• -76

• 20
