The instructor explains the inverse operations needed to isolate variables and provides examples to illustrate the process. An alternative method for solving equations is also discussed, offering students different approaches to find solutions. The tutorial emphasizes understanding integer operations and checking solutions for accuracy.

What is the inverse operation of subtracting 3?

• Subtracting 3

• Adding 3

• Multiplying by 3

• Dividing by 3

If w - 3 = -4, what is the value of w?

• 7

• -1

• 1

• -7

How do you check if w = -1 is a solution to w - 3 = -4?

• -1 + 3 = -4

• w + 3 = -1

• -1 - 3 = -4

• w - 3 = -4

What is the result of adding 5 to both sides of the equation m - 5 = -6?

• m = -1

• m = -11

• m = 11

• m = 1

How can you verify that m = -1 is a solution to m - 5 = -6?

• 1 - 5 = -6

• -1 + 5 = -6

• -1 - 5 = -6

• -1 - 5 = 6

What is the inverse operation needed to solve y + 8 = 4?

• Adding 8

• Subtracting 8

• Dividing by 8

• Multiplying by 8

If y + 8 = 4, what is the value of y?

• 12

• -12

• 4

• -4

How do you verify that y = -4 is a solution to y + 8 = 4?

• -4 + 8 = 12

• -4 - 8 = 4

• 4 + 8 = 4

• -4 + 8 = 4

What is the value of n if n + 5 = -2?

• -7

• 7

• -3

• 3

How can you check if n = -7 is the correct solution to n + 5 = -2?

• -7 + 5 = -2

• -7 - 5 = -2

• 7 + 5 = -2

• -7 + 5 = 2
