Solving an equation with parentheses

The video tutorial explains how to solve an equation with two variables by simplifying expressions, distributing negative signs, combining like terms, and solving the resulting equation. The process involves using the order of operations and properties of equality to find the value of N. The tutorial emphasizes the importance of checking solutions, although it is not demonstrated in the video.

What is the first step in simplifying the expression 8N - (2N - 3)?

• Combine like terms directly

• Multiply 8N by 2N

• Distribute the negative sign

• Add 2N and 3

How do you represent the negative sign outside the parentheses in the expression 8N - (2N - 3)?

• As a negative 1

• As a positive 1

• As a positive 3

• As a zero

After distributing the negative sign, what is the simplified form of 8N - (2N - 3)?

• 8N + 3

• 10N - 3

• 6N + 3

• 6N - 3

What is the next step after obtaining the equation 6N + 3 = 12?

• Divide both sides by 3

• Subtract 3 from both sides

• Add 3 to both sides

• Multiply both sides by 6

What is the final solution for N in the equation 6N = 12?

• N = 4

• N = 1

• N = 2

• N = 3
