Solving a multi step equation with brackets and parenthesis ex 18, 7n+2[3(1–n)–2(1+n)]=14

The video tutorial explains how to solve a complex equation involving brackets and parentheses. It begins by clarifying the role of brackets as grouping symbols similar to parentheses. The instructor demonstrates simplifying expressions inside brackets using the order of operations, then combines like terms. Finally, the video shows how to solve the resulting two-step equation, providing a clear example of handling multi-step equations with nested grouping symbols.

What is the primary purpose of using brackets in equations?

• To indicate multiplication

• To serve as another form of parentheses for grouping

• To separate different equations

• To add complexity to the equation

When simplifying an equation with brackets, which operation should be performed first?

• Multiplication

• Subtraction

• Division

• Addition

After simplifying inside the brackets, what is the next step in solving the equation?

• Divide by the largest number

• Multiply all terms by 2

• Combine like terms

• Add all the numbers

What is the result of combining the terms 7N and -10 in the equation?

• -3N

• -17N

• 3N

• 17N

What is the final solution for N in the equation?

• N = -4

• N = -3

• N = 4

• N = 3
