math 7- 4TH MID

it is a mathematical statement indicating that 2 algebraic expressions are equal

• Inequality
• Algebraic Equation

• Variable
• Function

it refers to the value of the variable that makes the equation true

• Solution
• Integral
• Derivative
• Root

it is an equation that can be written in the standard form ax + b = c.

• 3x = 15
• Linear Equation

• 4x = 20
• 5x = 25

ALGEBRAIC EQUATION OR ALGEBRAIC EXPRESSION: 3x - 18

• Equation

• Expressions

ALGEBRAIC EQUATION OR ALGEBRAIC EXPRESSION: 3x - 18 = 29

• Equation

• Expressions

A quantity is equal to itself. E.g: a = a

• a = b
• a = c
• a = x
• Reflexive Property

an equality that can be reversed. Example: if a = b, then b = a

• Reflexive property
• Transitive property
• Associative property
• Symmetric property

two quantities that are both equal to the same quantity are also equal

• Symmetric property of equality
• Reflexive property of equality
• Distributive property of equality
• Transitive property of equality

it is if the same quantity is added to both sides of the equation, the equation remains true. Example: a = b then a + c = b + c and a = c = b - c

• Addition property

• The equation becomes negative
• The equation becomes undefined
• The equation becomes false

if the same quantity is multiplied to both sides of the equation the equation remains true

• Property of Inequality
• Property of Division
• Property of Addition
• Property Multiplication
