Solving Linear Equations Concepts

The video tutorial explains how to solve basic algebraic equations using a balance scale analogy. It covers solving equations by isolating the variable X through addition and subtraction. The tutorial includes examples such as X + 4 = 12, X - 6 = 8, X + 6 = 4, and X - 3 = -1. It emphasizes the importance of performing the same operation on both sides of the equation to maintain balance. The video concludes with practice problems for viewers to solve independently.

What is the key concept to remember when solving equations using a balance scale analogy?

• Always add numbers to both sides.

• Multiply both sides by zero.

• Keep both sides of the equation balanced.

• Subtract numbers only from the left side.

In the equation X + 4 = 12, what operation should be performed to isolate X?

• Subtract 4 from both sides.

• Multiply both sides by 4.

• Divide both sides by 4.

• Add 4 to both sides.

How do you solve the equation X - 6 = 8?

• Divide both sides by 6.

• Multiply both sides by 6.

• Add 6 to both sides.

• Subtract 6 from both sides.

What is the result of solving X + 6 = 4?

• X = -10

• X = 10

• X = -2

• X = 2

In the equation X - 3 = -1, what should be added to both sides to solve for X?

• Add 3

• Add 4

• Add 2

• Add 1

What is the solution to the equation X + 8 = 2?

• X = 6

• X = -6

• X = 10

• X = -10

How do you solve the equation X - 3.5 = 4.8?

• Divide both sides by 3.5.

• Add 3.5 to both sides.

• Multiply both sides by 3.5.

• Subtract 3.5 from both sides.

What is the result of solving X - 3.5 = 4.8?

• X = 7.3

• X = 8.3

• X = 1.3

• X = 9.3
