The Equations and Inequalities: Solving the First Degree Equation in One Unknown

The video tutorial covers solving equations, especially when dealing with infinite substitution sets. It introduces properties of equality in different number sets and demonstrates how to solve equations using adding, subtracting, division, and multiplication properties. Examples are provided for each method, and the tutorial concludes with a summary of solving first-degree equations in one unknown.

What is a challenge when solving equations with infinite substitution sets?

• They take a lot of time.

• They require complex numbers.

• They have no solutions.

• They are only applicable in North.

How can you solve the equation X - 2 = 5 using properties?

• By subtracting 2 from both sides.

• By subtracting 5 from both sides.

• By adding 2 to both sides.

• By adding 5 to both sides.

What is the result of solving X + 2 = 5 using the subtracting property?

• X = 3

• X = 2

• X = 7

• X = 5

How do you solve the equation 5X = 15 using properties?

• Multiply both sides by 5.
